Create Tetrahedron Mesh

To create a tet mesh, TetMesh under Mesh Tools opens a panel as shown on the right. This allows to create tet mesh inside a closed volume of shells. The shells can be selected with Add shells. If they are triangular, PRIMER will create a tet mesh. If some shells are quadrilateral, PRIMER attempts to split these into triangles automatically if the option Auto Split Quads is active.
