About this Book

The MSC.Nastran 2001 DMAP Programmer's Guide is a replacement for and update of the former Version 70.7 DMAP Modules and Data Blocks book. The chapters have been rearranged to make it easier to print this guide in two volumes. Contained in the first volume is material occasionally referenced by the user: the introduction to DMAP, syntax and concepts, data block descriptions, and NDDL statement descriptions. The second volume contains material that is more frequently referenced: the DMAP Module descriptions. Many new and useful utilities were added in Version 2001 and are briefly described in “What's New in V2001 DMAP?” on page 48. Also, refer to the MSC.Nastran 2001 Release Guide for changes in DMAP module formats that would affect upward compatibility of users' DMAP alters from Version 70.7 to Version 2001. The editor would like to thank Ms. Wendy Webb for producing the electronic form of this guide and Mr. Don Truitt for his expertise in the document production software. The editor would like to also thank Michael Fischer for managing this effort and making this guide more widely available than previous editions. Mike Reymond, Editor February 2002

Introduction

1.1

Introduction

MSC.Nastran DMAP (Direct Matrix Abstraction Program) is a high-level language with its own compiler and grammatical rules. This section provides a summary description of the MSC.Nastran DMAP language, rules, and syntax. A DMAP program consists of a series of functional blocks called “modules,” each of which has a unique name and a specific function. Modules are executed sequentially; branching and looping operations are performed by DMAP control statements. Modules communicate through the MSC.Nastran Executive System (NES) via logical collections of data called “data blocks” and “parameters.” Data blocks come in two distinct forms: “matrices” that obey the rules of matrix algebra, and “tables” that represent a convenient collection of data items. Data blocks are given arbitrary names (mnemonic names are recommended) and have header and trailer information defining their characteristics. Parameters are scalar items used for specifying control, operation, or system characteristics. Modules can use “input parameters,” “output parameters,” or both. Input parameters affect the internal operation of the modules. Output parameters are used to control DMAP logic and/or to pass scalar information to subsequent modules. Data blocks and parameters can be written onto either scratch or permanent physical files. When the normal MSC.Nastran execution is completed, data blocks and parameters written to scratch files are erased, and those written to the permanent physical file are available for future use. The NDDL (MSC.Nastran Data Definition Language) designates whether a data block is scratch or permanent. A detailed description of the NDDL statements can be found in “NASTRAN Data Definition Language (NDDL)” on page 697. MSC.Nastran provides the user with a variety of prewritten solution sequences. These solution sequences consist of a series of DMAP statements. MSC.Nastran allows the user to modify prewritten solution sequences or to write his or her own solution sequences using DMAP. The compilation, linkage, and execution of a DMAP program is specified by executive control statements in the input file. The creation of and access to databases is specified by file management statements also contained in the input file. File management statements are described in the “File Management Statements” in Chapter 2 of the MSC.Nastran Quick Reference Guide.

The MSC.Nastran DMAP Language

1.2

The MSC.Nastran DMAP Language

The basic components, or objects, of the DMAP language are: Parameters Scalar quantities used to control the flow of DMAP execution and to communicate options and/or values to modules or functions. Tables or matrices represented by a symbolic name. Statements or modules that process parameters and/or data blocks as input and/or output.

Data Blocks Instructions

The basic syntax of the DMAP language is:

? The DMAP language uses free-field input format and is case insensitive. ? A physical entry consists of information in columns 1 through 72. Columns

73 through 80 can be used for comments, but these columns do not appear in the printed listing and are not stored on the database.

? For the specification of modules or statements, a parent entry continues to a

subsequent entry if it terminates in a comma [ , ] or a slash [ / ], or if it is missing a right parenthesis [ ) ].

? The dollar sign [ $ ] ends any DMAP instruction and causes all subsequent

data to be treated as commentary. The recommended convention is to terminate all DMAP instructions with a dollar sign.

? DMAP symbolic names are used to identify variable parameters, data

blocks, DBVIEW view-names, subDMAPs, or LABEL statements. A symbolic name is composed of alphanumeric characters 1 to 8 characters in length. The following characters are allowed: A through Z, and 0 through 9. The first character must be a character from A through Z.

Parameters

1.3

Parameters

Parameters can be either constants, variables, or expressions and can represent one of several types: Type Integer Real Complex Logical Character whole number decimal number that is a whole number and a decimal point, with an optional decimal fraction. a pair of real numbers representing the real and imaginary parts of a complex quantity represents either TRUE or FALSE a string of 1 to 80 characters Description Example(s) 10 or -4 27000. or 2.7E5 or 2.7D5 (1.1,2.3) or (1.D0,3.5D1) TRUE or FALSE 'GEORGE'

Also, the real and complex types are either single or double precision. The following table indicates the storage units required as a function of data type. One storage unit is the basic word size on a computer. Typically, a word is 32 bits long on a short-word computer and 64 bits on a long-word computer. Type Integer Real single precision Real double precision Complex single precision Complex double precision Logical Character No. of words 1 1 2 2 4 1 1 to 20

The type of a parameter must be declared in at least one of three ways: Constant Explicit Implicit Inherent in its specification or construction On a TYPE statement for variable parameters In a module’s parameter list for variable parameters

Parameters

Constant Parameters

A constant represents a fixed value and is a number (integer, real, or complex), logical, or character string.

Integer Constants

An integer constant is a whole number with no decimal point. Its form is snn where: s = a sign, plus (+) or minus (-) nn = a string of digits (0 through 9) s is optional if the sign is positive (+). A minus sign must be used to indicate a negative integer constant. The absolute value of an integer constant cannot be greater than 2

31

– 1 = 214748367.

Real Constants

A real constant is a whole number with a decimal point that can be followed by a decimal fraction and/or a decimal exponent. The complete form is: snn.ddEsee for single precision snn.ddDsee for double precision where: s = a sign, plus (+) or minus (-) nn, dd, ee = strings of digits (0 through 9) E or D = that snn.dd is multiplied by ee raised to the power of 10. E indicates single precision, and D indicates double precision. s is optional if the sign is positive (+). A minus sign (-) indicates a negative real constant or negative exponent. D is required to specify double precision. E is optional if no exponent is required and the constant is single precision. However, if either E or D is specified, then an integer must follow, even if the exponent is 0. Only the leftmost 14 digits in nn.dd are used by MSC.Nastran. Leading zeros are ignored in counting the leftmost 14 digits.

A complex constant is a pair of real constants separated by a comma and enclosed in parentheses. The first real constant represents the real part of the complex number, and the second real constant represents the imaginary part.

Logical Constants

A logical constant is specified as TRUE or FALSE.

Character Constants

A character constant is a string of 1 through 80 characters that may have embedded blanks. A character constant must also be enclosed by right hand single quotation marks.

Variable Parameters

A variable parameter is represented by a symbolic name, and its value may change during the DMAP execution. The name of a variable parameter does not have to be unique with respect to symbolic names for modules, data blocks, subDMAPs, or LABELs. The name of a variable parameter cannot be NOT, AND, XOR, OR, or EQV. Variable parameters can have their attributes (type, authorization, and default) set explicitly with a TYPE DMAP statement or implicitly by a module. (Variable parameters that are saved on the database must also be designated as NDDL parameters in the TYPE DMAP statement). Variable parameters that are not specified with a TYPE DMAP statement use the attributes from the DMAP instruction where the parameter first appears.

Value of a Variable Parameter

During a DMAP execution or when restarting a DMAP from the database, the value of a variable parameter is determined by the first applicable value on the following sequential list: 1. Value from the most recently executed assignment DMAP statement or the most recently executed save function (S,N prefix. See “DMAP Modules and Statements” on page 715). 2. Value from the PARAM Bulk Data entry, if the parameter NAME has the Y authorization. 3. Value saved on the database, if the parameter NAME is listed with an NDDL TYPE DMAP statement and the run is a restart.

7

Parameters

4. Value from the NAME=v, if present in a non-NDDL parameter TYPE instruction. This value is determined at DMAP compile time from the TYPE instruction (regardless of its location in DMAP) that contains the statement. 5. Default value from the NDDL, if the NDDL keyword is specified on the TYPE DMAP statement. Parameters listed in the NDDL always have a default value of zero, blank, or FALSE, unless a value is explicitly given in the PARAM NDDL statement. 6. Default value from the first occurrence of either a non-NDDL TYPE DMAP statement or a module with a MPL default value. Non-NDDL TYPE DMAP statements have a default value of zero, blank, or FALSE for real or integer, character, or logical parameters. 7. Default value is zero, blank, or FALSE for real or integer, character, or logical parameters. Determining the current value of a variable parameter is also summarized in the following table. NDDL TYPEd Not TYPEd

Bulk Data PARAM entry override, if parameter is type Y and has not been previously reassigned in an assignment (=) statement (unless the PVT module has been executed to reset the Bulk Data and Case Control PARAM entries). Value on the data base name=v from its first occurrence in a TYPE statement TYPE statement default MPL default of parameter first occurrence

NDDL default value

Predefined Variable Parameters

The program predefines the value of some variable parameters. It is not necessary to type these parameters with a TYPE DMAP statement, nor is it possible to change their type. We do not recommend changing these parameter values. The predefined variable parameters are: NAME ALWAYS NEVER VALUE -1 +1 TYPE Integer Integer

8

Parameters

NAME TRUE FALSE NOGO

VALUE TRUE FALSE 0

TYPE Logical Logical Integer

Initial values for variable parameters can be specified using the PARAM Bulk Data entry or the PARAM Case Control command. Parameter values from the Bulk Data Section are brought into the DMAP sequence via the IFP module. Parameter values from case control are brought into the DMAP sequence via the PVT module. The PVT module reads the case control PARAM commands and resolves parameter values specified in both the Case Control and Bulk Data Sections.

Recommended Parameter Type Specification

Follow these recommendations to produce a more readable DMAP sequence where all Y parameters and parameters with non-MPL defaults are specified on TYPE statements.

? If the parameter's value is to be specified in the Case Control or Bulk Data

Section, then type the parameter near the top of the DMAP sequence:

TYPE PARM,,type,Y,param_name $

? If the parameter's default value is defined on the NDDL PARAM statement

and you wish to use the NDDL default value, then type the parameter near the top of the DMAP sequence:

TYPE PARM,NDDL,type,Y,param_name $

? If the desired default value differs from the MPL default, then specify the

parameter and the default value on a TYPE statement:

TYPE PARM,,type,Y,param_name=default_value $

? Specify in module instructions, as needed, "/param_name/" or

"/S,N,param_name/"

? Do not use the following obsolete parameter prefix specifications in module

instructions:

/V,Y,param_name/ /S,Y,param_name/ /V,N,param_name/ /C,Y,param_name/ /C,N,param_name/

9

Parameters

For example, the following sequence is recommended for setting the TYPE of ALPHA:

TYPE PARM,,CS,Y,ALPHA=(1.,1.) $ TYPE PARM,,CS,N,ALPHAX $ . . . ALPHAX=ALPHA $ IF( FLAG ) ALPHAX=CMPLX(BETA,GAMMA) $ . . . ADD A,B/C/ALPHAX $

and the following is not recommended:

IF( FLAG ) PARAMR //'COMPLEX'//BETA/GAMMA/S,Y,ALPHA $ . . . ADD A,B/C/V,Y,ALPHA=(1.,1.) $

Expressions and Operators

An expression represents a single value and consists of one or more constant and/or variable parameters separated by operators. Expressions are classified as arithmetic, relational, logical, or character. Arithmetic expressions produce numerical values; relational and logical expressions produce logical values. An expression can contain intrinsic functions. An expression is specified:

? In the right hand side of an assignment (=) statement ? As arguments for intrinsic functions ? As logical expressions in control statements:

DO WHILE, IF, IF-THEN, ELSE IF-THEN

? As logical expressions in the WHERE clause of

DBVIEW, DBEQUIV, and DBDELETE statements.

10

Parameters

Arithmetic Operators

The allowable arithmetic operations are shown in the table below in the order of execution precedence. Parentheses are used to change the order of precedence. Operations within parentheses are performed first, with the usual order of precedence being maintained within the parentheses. Operator –,+ Operation Negative or Positive immediately preceded by exponentiation Exponentiation Negative or Positive Multiplication or Division Addition or Subtraction Sample Expressions X–Y Interpreted As X(–Y)

** –,+ *,/ +,–

–X**Y –X – Y X*Y+Z X+Y

–(X**Y) (–X) – Y (X*Y)+Z X+Y

In general, mixed mode expressions are not supported. For example, to compute A=B*C, where A and B are complex, but C is real, it is necessary to convert C to a complex number: A=B*CMPLX (C), where CMPLX is described under “Intrinsic Functions” in this section.

Character Operator

The only character operation is concatenation. Its form is shown below. Operator & Operation Concatenation Sample Expressions ‘ABC’ & ‘DE’ = ‘ABCDE’

11

Parameters

Relational Operators

Relational operators are used to compare two expressions. The result of the comparison is a logical TRUE or FALSE. When arithmetic and relational operators are combined in one expression, the arithmetic operations are performed first. The table below shows the allowable relational operators. Operator = <>,>< < > < > Relation Tested Equality Inequality Less than Greater than Less than or equal Greater than or equal Expression X=Y X<>Y, X><Y X<Y X>Y X<Y X>Y

Logical Operators

Logical operators perform tests on multiple relations or Boolean operations. A logical operator returns a result that is either TRUE or FALSE. The outcome of a logical operation is determined as shown in the table below. These outcomes are listed in order of precedence. Parentheses are used to change the order of precedence.

12

Parameters

Operations within parentheses are performed first, with the usual order of precedence being maintained within the parentheses. Operator NOT X TRUE FALSE X AND Y TRUE TRUE FALSE FALSE X OR Y TRUE TRUE FALSE FALSE X XOR Y TRUE TRUE FALSE FALSE X EQV Y TRUE TRUE FALSE FALSE Y n/a n/a TRUE FALSE TRUE FALSE TRUE FALSE TRUE FALSE TRUE FALSE TRUE FALSE TRUE FALSE TRUE FALSE Output FALSE TRUE TRUE FALSE FALSE FALSE TRUE TRUE TRUE FALSE FALSE TRUE TRUE FALSE TRUE FALSE FALSE TRUE

Data Blocks

1.4

Data Blocks

A data block is a table or matrix represented by a symbolic name. All data blocks are comprised of records. Each record can contain a variable number of words. The first record ("Record 0") is called the header record, of which the first two words (when concatenated) form the name of the data block. The third and subsequent words are not usually used. The subsequent records are sometimes called "data records." For tables the data record can contain a mixture of any type of data; i.e, real, integer, complex, character, etc. For matrices the data record corresponds to the nonzero values in the column of the matrix; e.g., record 3 corresponds to the nonzero values in column 3. The last record is called the trailer record and contains summary information about the table or matrix. More detailed descriptions of a data block’s records are appear in “Data Blocks” on page 51. Table Trailers In tables, the trailer record contains six words. The contents vary among the tables and are described in “Data Blocks” on page 51 at the end of the table’s description. Table trailers are printed when DIAG 15 is specified in the Executive Control or DIAGON(15) is specified in the DMAP sequence. Matrix Trailers In matrices the characteristics of a matrix are described in a twelve-word matrix trailer. Matrix trailers are printed when DIAG 8 is present in the Executive Control Section DIAGON(8) or is specified in the DMAP sequence. The contents of a matrix trailer are as follows:

Type is defined as one of the following: Type 1 2 3 4 Meaning Real, single precision Real, double precision Complex, single precision Complex, double precision

16

Data Blocks

Data Block Type and Status

The data block type depends on whether the data block is stored on a permanent or scratch DBset and whether its name appears on a TYPE DB statement. A DBset is a physical file that is a subdivision of the database; see Chapter 12 of the MSC.Nastran Reference Manual. There are three types of DMAP data blocks: Permanent NDDL Scratch NDDL Local Referenced on a TYPE DB statement and assigned to a permanent DBset through the NDDL Referenced on a TYPE DB statement and assigned to the SCRATCH DBset through the NDDL Not referenced on a TYPE DB statement and automatically assigned to the SCRATCH DBset.

At any point during a DMAP execution a data block is in one of the three following states: Generated Not generated Empty The data block has been created The data block has been deleted or is not yet created The data block has been created but has no data (or purged). In other words, the name of the data block is stored on a permanent DBset without any associated data.

Permanent blocks can have all states: generated, not generated, and empty. Empty data blocks are created when a module is executed, but no data is actually generated for the data block. For example, the ADD module has two inputs; if both inputs do not exist (not generated), then the output is empty or purged. Empty data blocks are required to support automatic restarts. A permanent data block can be explicitly purged with the PURGEX statement. Permanent data blocks can be deleted from the database with the DELETE statement. Scratch data blocks can have only two states: generated and not generated. These data blocks can be deleted with the DELETE or PURGEX statements.

17

Instructions

1.5

Instructions

A DMAP instruction can be classified as either a module or a statement. A module is similar to a "macro" function and, in general, processes data blocks as input and/or output. A module may also have parameters as input and/or output. A statement is any instruction that is not a module and that does not operate on data blocks.

Modules

A module instruction has the following form: the name of the module followed by a comma [,] and a list of input data block names separated by commas, a slash [/], a list of output data block names separated by commas, a slash, and a list of parameter (variable names or constants) separated by slashes: module_name , input_data_block_list / output_data_block_list / parameter_list $

The dollar sign [$] is required to terminate the module instruction. The modules are described in “Detailed Descriptions of DMAP Modules and Statements” on page 723. Most modules have a prescribed number of inputs, outputs, and parameters, which are defined in the Module Property List (MPL). The MPL is an internal MSC.Nastran table that prescribes the exact format of all modules--the number of input and output data block lists and the number, type, and default of the parameters in the parameter list. The MPL can be listed by specifying DIAG 31 in the Executive Control Section. The position of the data block and parameter names is critical to the proper execution of the module. Below is an example using the MPYAD module, which performs the following matrix operation:

[D] = SIGNAB*[A][B] + SIGNC*[C]

or

[D] = SIGNAB*[A]T[B] + SIGNC*[C]

where [A], [B], [C] and [D] represent matrices, and SIGNAB and SIGNC represent the sign to be applied to the product and additive matrices, respectively. The format of the MPYAD module is:

MPYAD , A , B , C / D / T / SIGNAB / SIGNC / PREC / FORM $

18

Instructions

where A, B, and C, represent the input data block names, D represents the output data block name, and T, SIGNAB, SIGNC, PREC, and FORM represent the parameter names. The MPL listing for the MPYAD and PARAML modules appears below: Listing 1-1 Module Properties List.

The MPL listing contains useful information under the following column headers: Header MOD-NAME IN OUT ID TYP Description Module name Number of input data blocks Number of output data blocks Parameter position type of parameter:

INT - integer RSP - real single precision RDP - real double precision CSP - complex single precision CDP - complex double precision BCD - character LOG - logical

DEFAULT

Default value of parameter

The other column headers are less important to the DMAP programmer. Some or all data blocks and parameters can be left unspecified (or purged), according to the module description in “Detailed Descriptions of DMAP Modules and Statements” on page 723. If a parameter is unspecified, then the default value is assumed and obtained from the MPL. For example,

19

Instructions

MPYAD

A , B , / D $

According to the MPYAD module description, if C is unspecified, then only the matrix multiplication of A and B is performed. Also, by default, T=0 and therefore A is not transposed. SIGNAB and SIGNC parameters are defaulted to 1 resulting in:

[D] = [A][B]

However, if no default is defined in the MPL, then a constant or variable parameter must be specified for the first parameter. For example,

-- NO DEFAULT --

on the PARAML module indicates there is no default value for the first parameter. The first comma after the module name can be omitted as long as the first input data block name is specified. For example, the ELTPRT module has the following format:

ELTPRT ECT,GPECT,BGPDT,UNUSED4,EST,CSTM,MPT,DIT,CASECC/ VELEM/PROUT/S,N,ERROR $

To obtain a printout of the elements connected to each grid point, only GPECT and BGPDTS need to be specified; however, a comma must also be specified after the module name:

ELTPRT , ,GPECT,BGPDTS,,,,,,/ $

In addition, trailing commas can be left unspecified:

ELTPRT , ,GPECT,BGPDTS,,,,,,/ $

Parameters can be specified on a module as: input only input and output output only Each module has its own rules for parameter specification, as described in “Detailed Descriptions of DMAP Modules and Statements” on page 723. If a parameter is specified as input, then either a constant or variable can be specified. Note that character strings or variables specified for parameters are limited to eight characters in length. For example, the first parameter of the ADD module specifies a scalar multiplier of 1+2i on the first input matrix:

ADD A , B / C / (1.,2.) $

20

Instructions

or ALPHA:

ADD A , B / C / ALPHA $

If a parameter is to be used as both input and output, or output only, then a variable name must be specified and preceded by S, N,. For example, on the PARAML module, the fourth parameter, TERM, is an output parameter:

PARAML A // 'DMI' / 4 / 7 / S, N, TERM $

TERM is the value of matrix A at column 4 and row 7, which will be returned by the PARAM module for later use in the DMAP program. If the S,N prefix is omitted, then TERM is assumed to be input only, no fatal message is issued, and the TERM value is incorrect.

Statements

A statement is any instruction that is not a module and that typically does not produce output data blocks from input data blocks or parameters. Another distinction is that a statement has no definition in the MPL (Module Property List). The different types of statements are: Assignment (=) Function Control Declarative Data Base Function

Assignment Statement

The assignment statement evaluates an expression and assigns the resulting value to a variable parameter. This statement has the following form:

v = e $

where v is a variable parameter name, and e is an expression. The dollar sign [$] is required to terminate the statement. Assignment statements are arithmetic, logical, or character, depending on the type of the variable parameter. The type of the variable and the expression must be the same. In other words, no mixed mode specification is allowed.

21

Instructions

Type conversions can be performed with the INT, REAL, CMPLX, ITOL, and LTOI DMAP functions. For character assignment statements, if the length of the expression does not match the size of the variable, the expression is adjusted as follows:

? If the expression is shorter than the variable, the expression is padded with

enough blanks on the right before the assignment takes place to make the sizes equal.

? If the expression is longer than the variable, characters on the right are

truncated to make the sizes the same.

Function Statement

Functions can only appear within an arithmetic or logical expression; they cannot be referenced within module or CALL statements. Execution of the function causes the evaluation of the function and returns a value to the referencing expression. Some functions, however, may appear as a DMAP statement without appearing in an arithmetic or logical expression. These functions are DIAGON, DIAGOFF, NOOP, PUTSYS, PUTDIAG, RDIAGOFF, and RDIAGON. The type of the value returned from a function is dependent on the type of the argument(s) supplied, in addition to the functional operation. In general, the precision (single, double) and form (integer, real, complex) of the result returned by the function carries at least as much information as the arguments supplied. For example, ACOS(X) is typed as follows: X I RS RD CS CD ACOS(X) RS RS RD CS CD

Returned values for character functions can be processor dependent.

For complex arguments only one value can be specified. The result is the value and type of the argument. Integer, real single, and real double values are allowed with two arguments only. The results are complex double if either or both arguments are real double. The results are complex single if neither argument is real double.

Control Statement

The MSC.Nastran DMAP language contains control statements that perform conditional branching and looping similar to those found in the FORTRAN programming language. The control statements are: Conditional Execution Unconditional Branching Conditional Branching Looping Calling SubDMAP Operations Termination Conditional Execution—IF Statement The IF statement conditionally executes a single DMAP instruction:

IF ( logical expression ) instruction $

IF JUMP and LABEL IF()THEN, ELSE IF()THEN, ELSE, and ENDIF DO WHILE and ENDDO SUBDMAP, CALL, and RETURN EXIT and END

In other words, if the logical expression is true, then the instruction is executed. Instruction is any DMAP module or statement, except a control statement or the FILE, DBVIEW, TYPE and SUBDMAP statements. Examples include:

IF ( NOGOA=-1 ) ADD GOAT,GOAQ/GOA $ IF ( ERRFLAG<0 ) CALL ERROR //S,GO/ERROR $ IF ( A AND B ) X=2*Y $

Unconditional Branching—JUMP and LABEL Statements The JUMP and LABEL statements are analogous to the GO TO and CONTINUE statements in FORTRAN, except the LABEL statement cannot appear above the JUMP statement. For example,

JUMP n $ . . . LABEL n $

where n is character string, up to eight alphanumeric characters in length, and the first character must be alphabetic.

34

Instructions

JUMP and LABEL can be used to jump out of a DO WHILE loop or IF()THEN block, but JUMP and LABEL cannot be used to jump into a DO WHILE loop or IF()THEN block. JUMP can appear on an IF statement; however, in this case we recommend an IF()THEN statement. Conditional Branching—IF ( ) THEN Statement The IF ( ) THEN operation has the following form: 1. IF(expression)THEN $

. . DMAP executed if expression is TRUE . ENDIF $

2. IF(expression)THEN $

. . DMAP executed if expression is TRUE . ELSE $ . . DMAP executed if expression is FALSE . ENDIF $

3. IF(expression 1)THEN $

. . DMAP executed if expression . ELSE IF(expression 2)THEN $ . . DMAP executed if expression . and expression 2 is TRUE ELSE IF(expression n)THEN $ . . DMAP executed if expression . n-1 are FALSE and expression ELSE $ . . DMAP executed if expression . n are FALSE ENDIF $ 1 is TRUE

1 is FALSE

1 through expression n is TRUE

1 through expression

The expressions in the above examples are relational and/or logical operations that result in a logical output of either TRUE or FALSE. The allowable relational operators are discussed under “Expressions and Operators” on page 9. Looping—DO WHILE ( ) Statement

35

Instructions

DO WHILE(expression) $ . . . ENDDO $

The expression in the above example is a relational and/or logical operation that results in a logical output of either TRUE or FALSE. The allowable relational and logical operators are discussed under “Expressions and Operators” on page 9. There is no limit to the allowable number of DO WHILE statements. Scratch NDDL and local blocks (see (p. 16)) which are first referenced and created inside a DO WHILE loop are automatically deleted at the end of the loop (see page (p. 40)). The FILE statement with the APPEND or SAVE keyword may be specified to override the automatic deletion in order to "save" a scratch data block for subsequent passes through the DO WHILE loop. See the APPEND and FILE statement descriptions in “DMAP Modules and Statements” on page 715 for examples. Calling SubDMAP Operations—SUBDMAP, CALL, and RETURN Statements The CALL and SUBDMAP statements allow for the definition of DMAP subprograms called subDMAPs. The RETURN statement can be used in a subDMAP to return to the calling subDMAP. The SUBDMAP statement denotes the beginning of a DMAP subprogram; either a main subDMAP or a called subDMAP. A main subDMAP can be invoked with the SOL Executive Control statement and cannot have any arguments. A called subDMAP may or may not have arguments and is invoked by a CALL statement in another subDMAP, defined as the calling subDMAP. The form of the SUBDMAP and CALL statements are:

SUBDMAP subDMAP-name [I1,I2,I3,.../ O1,O2,O3,.../ P1/P2/P3/... $] [I1,I2,I3,.../ O1,O2,O3,.../ [S,]P1/[S,]P2/[S,]P3/...]

CALL

subDMAP-name

$

where subDMAP-name is the name of a subDMAP. The arguments Ii, Oi, and Pi are the list of input data block names, output data block names, and variable parameter names or constant parameters. The specification of arguments is optional. If arguments are specified, the CALL and SUBDMAP statements must agree in order, in number, and, for parameters only, in type.

36

Instructions

The linker checks for correspondence of the arguments. The linker also checks for consistent parameter authorization if NASTRAN SYSTEM(147)=1. In addition, a view-name defined by the DBVIEW statement cannot be specified in the argument list. If an argument list is specified on the SUBDMAP statement, no argument can be left unspecified. Also, all parameter arguments must be variable parameter names. Any data block argument on the CALL statement can be left unspecified. Inside the called subDMAP, the data block argument is treated as purged. All parameters must be specified on the CALL statement, but the parameters can be either a variable parameter name or a constant value. Also on the CALL statement, parameter values, such as qualifiers or local parameters (which are computed in the called subDMAP), can be returned to calling subDMAP by preceding the parameter name with "S,". This method is called the save option. The save option is not required for parameters specified on TYPE PARM,NDDL statements in the called subDMAP. The RETURN statement can be specified anywhere in the subDMAP. This statement terminates execution of the current subDMAP and resumes execution of the calling subDMAP. If the RETURN statement is not specified in the subDMAP, all DMAP execution is terminated at the END statement (discussed in the next section). Below is an example using the SUBDMAP, CALL, and RETURN statements. The main subDMAP is called MAIN and contains two calls to subDMAP TEST. In the first CALL to subDMAP TEST, the second input and output data blocks are marked as ",," and are not generated. The value of Q1 is returned as computed in TEST. In both CALL statements, the value of P2 is returned from TEST. Although Q3 may have changed in subDMAP TEST, Q3’s value is not returned to MAIN. In the second call a constant value of 0 is specified for P1.

SUBDMAP MAIN $ Main SUBDMAP TYPE PARM,,I,N,Q1=5 $ TYPE PARM,,I,N,P1,P2,P3,Q3 $ . . . CALL TEST A,,C/D,,F/P1/S,P2/S,Q1 $ . . . CALL TEST A,B,C/I,J,K/0/S,P2/Q3 $ . . . END $

SUBDMAP TEST X,Y,Z/L,M,N/A1/A2/A3 $ TYPE PARM,,I,Y,A3 $ TYPE PARM,,I,N,A1,A2 $ . . . RETURN $ END $

The following should also be noted:

? The data block names specified on the SUBDMAP statement argument list

are called local names and will not appear in any diagnostic output. Diagnostic output, such as data base directory print or DIAG 8, only indicates the top-level name. The top-level name is the name of the data block in the highest CALL statement in which it appears. In the example above the local names are X, Y, Z, etc., and the top-level names are A, B,C, etc.

? All input data blocks specified on a CALL statement must have been

previously defined by output from a module in the calling subDMAP or from a previously specified CALL statement, or specified on TYPE DB statements. See the “TYPE” on page 1427 statement.

? Recursive subDMAP calls are allowed; i.e., a subDMAP can call itself either

directly or indirectly.

? The last parameter in the argument list must not be followed by a slash (/).

Termination—EXIT and END statements Both EXIT and END statements terminate the DMAP execution. However, the EXIT statement can be specified at any time in a subDMAP, and the END statement can be specified only once and must appear at the end of a subDMAP. The following example demonstrates the use of both statements:

SUBDMAP AAA $ . . (some DMAP instructions) . IF(ERROR)EXIT$ . . (some DMAP instructions) . END $

If ERROR is true, the EXIT statement is used to terminate the subDMAP. The END statement is required and must be the last statement in the subDMAP.

“Output from a Previous Module” Rule

1.6

“Output from a Previous Module” Rule

If a data block has already been specified as output by a previous module and is specified as output from another module, User Fatal Message 1126 is issued during execution. This principle is called the “output from a previous module” or “output twice” rule. This rule is waived if any of the following is true:

? The data block is specified on a FILE statement with the APPEND or

OVRWRT keyword.

? The data block is TYPE’d (specified on a TYPE DB statement), and its current

qualifier values are different from the qualifier values given at the time of the previous module execution.

? The data block is specified as output on a CALL statement and TYPE’d.

40

Automatic Deletion of Scratch Data Blocks

1.7

Automatic Deletion of Scratch Data Blocks

Scratch NDDL and local data blocks are stored on the SCRATCH DBset (p. 16). A DBset is a physical file that is a subdivision of the database; see Chapter 12 of the MSC.Nastran Reference Manual. To minimize the size of the SCRATCH DBset, module scratch files are automatically deleted upon completion of the module and DMAP scratch data blocks are automatically deleted after the DMAP instruction in which they are used last. The location of this DMAP instruction is called the last-time-used (LTU). An LTU is assigned to every data block. When the LTU of an Scratch NDDL data block is reached, the data block is deleted if the current qualifier values match. If the data block’s LTU is skipped, then the entire family is deleted, regardless of the current qualifier values. Special rules apply for data blocks specified in the following situations:

? For a scratch data block specified before a loop and last used inside the loop,

the LTU is extended to the bottom of the loop (e.g, ENDDO), meaning that the data block is deleted when the loop is exited. If the data block is Scratch NDDL, the entire family is deleted, regardless of the current qualifier values.

? For a local data block created inside a DMAP loop and last used after the

loop, the data block is deleted after the next execution of the top of the loop, e.g., DO WHILE, even though the data block’s LTU is located after the loop (i.e., when the loop is exited). Thus, the last generated data block can be used after the loop exits.

? For a scratch data block created and last used inside a DMAP loop, the FILE

statement with the SAVE keyword extends the data block’s original LTU to the bottom of the loop; otherwise, the data block is deleted at the original LTU within the loop.

? For a Scratch NDDL data block used in a DBVIEW statement, the data block

is deleted at the LTU of the view name or the data block name, whichever is last. DlAG 57 prints the LTU information of all data blocks and a message indicating when they are deleted.

Preface Modules and SOLution 100

1.8

Preface Modules and SOLution 100

The preface modules IFP1, XSORT, IFPi, DTIIN, and DMIIN generate data blocks related to the Case Control, Bulk Data, and DMI or DTI entries. These modules are specified at the beginning of all MSC.Nastran Solution Sequences. SOLution 100 is also provided for the DMAP writer who wishes to execute his/her DMAP sequences without having to specify the Preface modules IFP1, XSORT, and IFPi. The DMAP writer needs to insert the following DMAP statements in the Executive Control of the input data: 1. SOL 100

COMPILE USERDMAP ALTER 2

2. If matrices or tables are to be input with DMI or DTI Bulk Data entries, the DMIIN or DTIIN modules must be specified by the DMAP writer. For example, the following DMAP statements generate matrices A, B, C, D, and E and tables TA, TB, TC, TD, and TE:

DMIIN DMIIN DMI,DMINDX/A,B,C,D,E,,,,,/ $ DMI,DTINDX/TA,TB,TC,TD,TE,,,,,/ $

Data block names A, B, C, D, E, TA, TB, TC, TD, and TE can now be referenced in subsequent DMAP statements. 3. The DMAP writer’s DMAP sequence can now be inserted. 4. TYPE statements that reference data blocks or parameters defined in the NDDL of the structured solution sequences (SOLutions 101 through 200) can also be inserted.

42

Processing of User Errors

1.9

Processing of User Errors

Modules used in Phase I of the superelement SOLution sequences (SOLs 101 through 200) include an option to continue processing after fatal errors are discovered and printed in the output file. The module completes processing as best it can and then sets a special integer parameter named NOGO to -1. The output files may be purged or incomplete. If no errors are discovered, NOGO is set to 0. The DMAP writer can choose to branch to the end of a loop or take other actions when error conditions are discovered. This option is selected by setting SYSTEM cell 82 to 1. Users who insert alters into Phase l should be aware of this option. An example of this option, based on the method used in SOLs 101 through 200, is:

PUTSYS(1,82) $ALLOWS DMAP TO FIELD NOGO FLAGS . . . GP2 GEOM2S,EQEXINS,,GEOM2A,EPTA/ECTS,ECTAS $ IF ( NOGO = -1 ) THEN $ CALL ERRPH1 //SUBDMAP/0/-1/DUMMY $ LOOPER RETURN $ CONTINUE TO NEXT SE ALTHOUGH ENDIF $ ERROR FOUND IN CURRENT SE . . . PUTSYS (0,82) $ DISALLOWS DMAP TO FIELD NOGO FLAGS

The GEOM2S file contains element connectivity data. If the GP2 module detects errors in this data, it will set NOGO to -1. Modules that presently have this option include:

DCMP DECOMP DYCNTRL EMG GP2 GP3 GP4 LCGEN MGEN MTRXIN SEDR SELA SEMA SSG1 TA1

SubDMAPs DBMGR, DBSTORE, and DBFETCH

The DBMGR, DBSTORE, and DBFETCH module capabilities prior to Version 66 have been replaced by subDMAPs, as described below.

CALL CALL CALL DBMGR //OPT/P2/P3/P4/P5/P6/DB1/DB2/DB3/DB4/DB5 $ DBSTORE DB1,DB2,DB3,DB4,DB5//Q1/Q2/DBSET/COND $ DBFETCH /DB1,DB2,DB3,DB4,DB5/Q1/Q2/FLAG/0/S,SUCCESS $

The complete descriptions can be found in “DMAP Modules and Statements” in Chapter 4 under subDMAPs DBFETCH, DBMGR, and DBSTORE. Prior to Version 66 data blocks could be stored, fetched, and manipulated from the database via the DMAP modules DBSTORE, DBFETCH and DBMGR. In Version 66 these modules were removed in favor of a more robust and automatic capability. To help users store data blocks that are not already defined in the NDDL, a set of subDMAPs are available that emulate most of the capabilities in those modules. The subDMAPs and their capabilities are: CALL DBSTORE CALL DBFETCH CALL DBMGR store data blocks on the database retrieve data blocks from the database perform various functions related to data blocks stored using CALL DBSTORE

DIAG 47 can be specified in the Executive Control Section to print diagnostics related to these operations. These subDMAPs are stored in the delivery database and do not have to be compiled by the user if they are being used in any MSC.Nastran solution sequences. For example:

SOL 101 DIAG 47 COMPILE SEDRCVR ALTER ’AFTER ELEMENT STRESS’ CALL DBSTORE OES1,,,,//0/SEID/’ CEND

WHERE and CONVERT Clauses

1.11

WHERE and CONVERT Clauses

The WHERE clause is used in the selection of items (data blocks and parameters) on the DBDICT, DBLOCATE, DBLOAD, and DBUNLOAD statements. The CONVERT clause modifies qualifier values of items selected by the WHERE clause on the DBLOCATE and DBLOAD statements. The WHERE and CONVERT clauses specify values for PROJECT, VERSION, qualifiers, and DBSET. PROJECT specifies the project-ID that is originally defined on the PROJECT FMS statement at the time the project is created. VERSION specifies the desired version-ID under the project-ID. Qualifiers are used to uniquely identify items on the database with the same name. For example, data block KAA has SEID as one of its qualifiers, which is the superelement ID. An item may have more than one qualifier and the collection of all qualifiers assigned to an item is called a path. All data blocks and parameters with qualifiers are defined in the NDDL Sequence ( see “NASTRAN Data Definition Language (NDDL)” on page 697). Data blocks and parameters are defined on the DATABLK and PARAM NDDL statements. The DATABLK and PARAM statements specify the name of the data block, parameter, and also its pathname. The pathnames are defined on the PATH NDDL statement, which lists the qualifiers assigned to the path. Qualifiers are defined on the QUAL NDDL statement. DBSET specifies the desired DBset. The DBset of an item is specified after the LOCATION keyword on the DATABLK and PARAM NDDL statement. The format of the WHERE clause is: WHERE (where-expr) where-expr is a logical expression that specifies the desired values of qualifiers, PROJECT, VERSION, and DBSET. If the result of the logical expression is TRUE for an item on the database then the item is selected. For example, WHERE(VERSlON=4 AND SElD<>2 AND SElD>0) selects all items under version 4 for all values of SEID greater than 0 except 2. A simple where-expr is a comparison using the following relational operators =,>‘<‘ <, >, or utortu. For example, SElD>0 means if SEID is greater than zero, then the logical expression is true. Several simple where expressions may be joined into one where expression by the following logical operators: AND, OR, XOR, and EQV. The NOT operator may be used to negate a where expression. For example, NOT(SEID>0) is the same as SEID>0. Arithmetic operations and DMAP functions may also be specified in the where expression (see “Expressions and Operators” on page 9).

46

WHERE and CONVERT Clauses

If a qualifier in a where-expr is not a qualifier in the path of a specified item, then the where-expr is set to FALSE. If the where-expr does not contain a specification for all qualifiers in the path of an item, then the unspecified qualifiers will be wildcarded (i.e., quali=*, all values will be selected.) The default values of qualifiers, PROJECT, VERSION, and DBSET are described under the statement in which the WHERE clause is specified. Examples of the WHERE clause are: 1. Select all items in the database for all superelements except 10 and 30 from Version 1. WHERE (VERSION=1 AND SEID>0 AND NOT(SEID=10 OR SEID=30)) 2. Select all entries in database on DBSET=DBALL from all projects and versions. WHERE(PROJECT=PROJECT AND VERSlON>0 AND DBSET=’DBALL’) The CONVERT clause modifies project- and version-ID, DBset-name (see “INIT” on page 83 of the MSC.Nastran Quick Reference Guide statement), and qualifier values of items selected by the WHERE clause on the DBLOCATE and DBLOAD statements. It contains one or more assignment statements separated by semicolons. The format of CONVERT clause is: CONVERT(PROJECT=project-expr; VERSION=version-expr; , DBSET=DBset-expr;quali=qual-expri[;...]) The PROJECT and VERSION statements modify the project-ID (see “PROJ” on page 88 of the MSC.Nastran Quick Reference Guide statement) and version-ID. The DBSET statement modifies the DBset-name. The value of quali will be replaced by qual-expri for selected items that have quali in their path. qual-expri is any valid expression (see “Expressions and Operators” on page 9 containing constants or any qualifier name defined in the path of the item. If qual-expri contains names of qualifiers not in the path of the selected item, then a fatal message is issued. If project-expr and/or version-expr produces a project- or version-ID which does not exist, then one will be created. Also, all version-lDs less than version-expr that do not exist will be created; but they will be “empty.”

47

WHERE and CONVERT Clauses

Examples of the CONVERT clause are: 1. Set qualifiers SEID, PEID, and SPC to constants 10, 20, 102 respectively. CONVERT(SEID=10;PEID=20;SPC=102) If more than one value of a qualifier is found for an item by the WHERE clause, then each value is processed in qual-expri to define the new qualifier value for each of the selected items. In the example below, if the original values of PEID were 1, 2, and 3; then the new values for the SElD qualifier will be 2, 4, and 6. 2. Set all values of qualifier SElD to be twice the value of the PEID qualifier. CONVERT(SElD=2*PElD)

Matrix Data Blocks

The rows and columns of most matrices correspond to degree-of-freedom sets which are defined in the USET table. Matrices are usually named according to __rc where r and c are the names of the degree-of-freedom sets for the row and column, respectively. For example, the rows and columns of KFS correspond to the f-set and the s-set. The rows and columns corresponding to degree-of-freedom sets are ordered according to ascending internal point identification number sequence. This is the same as the external (user-assigned) grid point identification number sequence unless resequencing is requested (PARAM,OLDSEQ,>-1). Some matrices are also named with pseudo-degree-of-freedom set names. W – The set omitted after auto-omit (a-set combines x-set and w-set) X – The set retained after auto-omit (complement of w-set) J – Superelement interior degrees-of-freedom; for example, KJJ and PJ H – Modal degrees-of-freedom; for example, PHDH, MHH, PHF and UHF In some matrices the columns correspond to subcases, normal modes, time steps, or forcing frequencies. These matrices are usually related to loads and solutions and named __r__ where r is the name of the degree-of-freedom set. For example, PG is static loads applied to the g-set and PHA is the a-set eigenvector matrix. In frequency and transient response, a "F" or "T" may also be added to the name. For example, UDF and UDT, are the solution matrices at the d-set for frequency and transient response. Analysis Type Linear Statics Nonlinear Statics Normal or Complex Eigenvalues Frequency Response Transient Response Columns correspond to ascending Subcase identification number Loop identification number Mode number Subcase ID and Forcing frequency value Time step value

In transient response analysis, the columns of the solution matrix U_T correspond to "time step triplets". The first column in the triplet represents displacement, then velocity and acceleration. The triplet is then repeated for each time step. For example, if there are 10 time steps, then U_T will have 30 columns. If multiple TSTEP command subcases are requested then there will be a separate solution matrix for each subcase.

54

The columns of the dynamic load, MPCForce, and SPCForce matrices; P_T, QM_T, and Q_T, correspond to time step and, using the example above, they will each have 10 columns. In frequency response analysis, the columns of the dynamic load, MPCForce, SPCForce and solution matrices; P_F, QM_F, Q_F, and U_F, correspond to forcing frequency. If multiple dynamic load (DLOAD) subcases are requested with NFREQ number of forcing frequencies, the first NFREQ columns represent the first DLOAD subcase and NFREQ frequencies, the second NFREQ columns the second subcase, etc. For example, if an analysis is performed with four forcing frequencies and three DLOAD subcases, then the solution matrix will have 12 columns in which the first 4 columns correspond all forcing frequencies in the first subcase. If multiple FREQUENCY command subcases are requested then there will be a separate solution matrix for each subcase. For a description of matrix trailers see “Data Blocks” on page 13.

Table Data Blocks

This section discusses common attributes across several tables:

? IFP Tables ? OFP Tables ? Element types

See “Table Descriptions” on page 74.

IFP Tables

The IFP module processes the Bulk Data Section and creates data blocks which contain images of each Bulk Data entry. Then the modules IFP2 through IFP9, MODEPT, MODGM2, GP0, SEQP, and MODGM4 create pseudo-images based on the presence of elements used in hydroelastic, axisymmetric, laminated composite, composite beam, acoustic, hyperelastic, beam library and p-version analyses. For example, the IFP6 module converts PCOMP and MAT8 images to MAT2 and PSHELL pseudoimages. All of the tables produced by these modules are also called "IFP Tables". In an IFP Table there is one record written for each image type present in, or derived from, the Bulk Data Section and that record contains all of the images for that type. If the image type is not present, then no record is written.

IFP Table Header Words and Trailer Bits

The first three words in all IFP Tables uniquely identify or label the contents of the record and are called "header words". The second header word indicates a bit position, called a "trailer bit", in the table trailer. The trailer bit indicates the presence of record type in the data block; i.e., if the record is present in the table, then the bit is turned on in the trailer. There are a total of 176 trailer bits. The first 96 trailer bits correspond to bit positions 1 through 16, numbered from the right, in each trailer word and beginning with trailer word 1. The second 80 trailer bits correspond to bit positions 17 through 32, numbered

56

from the right, in each trailer word and beginning with trailer word 1. The table below shows that correspondence between a trailer bit and its word and bit location in the trailer. Trailer Bit 1 – 16 17 – 32 33 – 48 49 – 64 65 – 80 81 – 96 97 – 112 113 – 128 129 – 144 145 – 160 161 – 176 Location in Trailer Word 1 2 3 4 5 6 1 2 3 4 5 Position 16 – 1 16 – 1 16 – 1 16 – 1 16 – 1 16 – 1 32 – 17 32 – 17 32 – 17 32 – 17 32 – 17

For example, the GRID record in the GEOM1 data block is assigned to trailer bit 45 which corresponds to the 4th bit position, numbered from the right, in trailer word 3. Based on the trailer bit, the following FORTRAN statements may be used to determine the corresponding trailer word and bit position: WORD = MOD(TBIT-1,96)/16 + 1 BIT = 16*(1+TBIT/97) - MOD(TBIT-1,16) where TBIT = trailer bit from second word of header record WORD = trailer word BIT = trailer word bit position numbered from the right and all variables are defined as integers.

57

OFP Tables

The header record of all OFP tables contains codes which indicate how the output should be labeled, formatted, and printed. Word 1 2 9 11 Name approach_code table_code format_code stress_code Contains Analysis type and output device type(s) Header, labeling, and sort types Data types (real or complex) Stress/strain, von Mises/max. shear, straincurvature/strain-fiber flags.

Approach_Code

Approach_code indicates analysis type and device type(s). 1. Analysis type is equal to approach_code/10 indicates Type 1 2 3 4 5 6 7 8 9 10 11 Statics Normal modes or buckling (real eigenvalues) Differential Stiffness 0 Differential Stiffness 1 Frequency Transient Pre-buckling Post-buckling Complex Eigenvalues Nonlinear Statics Geometric Nonlinear Statics Description

2. Device type(s) are extracted from the bit pattern equal to MOD(approach_code,10). The bits numbered from the right are: Bit 1 2 3 Description Print Plot Punch

59

Therefore, MOD(approach_code,10) can be one of the following values: Value 0 1 2 3 4 5 6 7 Examples: Approach_code 61 15 106 Description print transient response results print and punch statics results plot and punch nonlinear statics results Device Type(s) None Print Plot Print and plot Punch Print and punch Plot and punch Print, plot, and punch

60

Table_code

Table_code indicates basic table content (displacements, stresses, etc.), data format (Real or complex), and sort type (SORT1 or SORT2). 1. MOD(table_code,1000) indicates table content; e.g., displacements, stresses, etc. Type 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 OES OELOF1 Chapter 2 Name OUG OPG OQG OEF OES LAMA OUG none OEIGS OUG OUG OPG OGPWG OUG OUG OUG OUG OEE OGF Description Displacement Vector Load Vector SPCforce or MPCforceVector Element Force(or Flux) Element Stress(or Strain) Eigenvalue Summary Eigenvector Grid Point Singularity Table (Obsolete) Eigenvalue Analysis Summary Velocity Vector Acceleration Vector Nonlinear Force Vector Grid Point Weight Generator Eigenvector (Solution Set) Displacement Vector (Solution Set) Velocity Vector (Solution Set) Acceleration Vector (Solution Set) Element Strain Energy Grid Point Force Balance Stresses at grid points (from CURV??)

2. Data format and sort types is extracted from the bit pattern equal to table_code/1000. Bits numbered from the right are: Bit 1 2 Description SORT2 (on) flag Complex (on) flag

62

Therefore, table_code/1000 can be one of the following values: Value 0 1 2 3 Examples: table_code 4 5 1005 2010 3005 Description Real Force in SORT1 Real Stress/Strain in SORT1 Complex Stress/Strain in SORT1 Real Displacements in SORT2 Complex Stress/Strain in SORT2 Sort Type SORT1 SORT1 SORT2 SORT2 Real Complex Real Complex Data Format

Format_code

Format_code is somewhat redundant and may conflict with table_code. In regards to real or complex, table_code/1000 always overrides format_code. However, when table_code indicates complex data, then format_code is used to determine between real/imaginary and magnitude/phase output. Value 1 2 3 Data Format Real Real/Imaginary Magnitude/Phase

Stress_code

In the OES data block description, word 11 (stress_code) of the header record determines the following:

? Octahedral (or maximum shear) or Hencky-von Mises. ? Stress or strain.

63

? if the strain is curvature or fibre.

Stress_code is a bit pattern and the bits numbered from the right are: Bit 1 2 3 4 Description Hencky von Mises (on) flag Strain (on) flag Strain/curvature (on) flag Same as bit 2

Therefore, stress_code can be one of the following values: Value 0 1 10 11 14 15 On bits 0000 0001 1010 1011 1110 1111 Description Stress maximum shear or octahedral Stress von Mises Strain Curvature maximum shear or octahedral Strain Curvature von Mises Strain Fibre maimum shear or octahedral Strain Fibre von Mises

In the OQG data block description, stress_code can be one of the following values: Value 0 1 Description SPCForce MPCForce

Element Type

Some tables reference an element type number. For example, EST, KDICT, OES, and EGPSF. The element type numbers are unique across all tables but do not necessarily appear in all tables. Some element types are pseudo-elements for data recovery purposes only; e.g., see types 85 through 98, 100, 144, and 201 through 223.

Table Descriptions

Table descriptions are arranged alphabetically by the generic name of the data block. A data block description may encompass descriptions of several data blocks from different modules. For example, the OES data block description describes data blocks OES1, OES2, OESNL, OSTR1, and OES1C which are output by the SDR2, SDR3, SDRNL, and SDRCOMP modules. The generic name of a data block also appears in the “Data Block Glossary” on page 548 at the end of “DMAP Modules and Statements” in Chapter 4.
