Trim with line Allows you to trim/split surfaces using a line (or a group of lines). In this case, HyperMesh r creates a temporary surface by sweeping the selected lines along a vector. You can choose the direction of this vector to be either normal to the surface selected or along a user-de?ned vector direction. The original surfaces are then trimmed at the intersection of these surfaces to the temporary surface. These trimming operations can split a surface into multiple surfaces 35.

Firstly, all shell elements should enclose a volume, which means that no free edges should exist. Secondly, there are no duplicated elements or T-connections in the model. Finally, to get a ?ne-quality tetra mesh, the quality of the shell mesh mush be ensured. 42.
