generate_mesh

Turn a committed CAD part into a CalculiX-ready tetrahedral finite element mesh with gmsh, check its quality, and identify the fixed and loaded faces by their real coordinates. Use when the user asks to mesh a part, prepare a part for FEA or thermal analysis, refine or coarsen a mesh, or find which mesh surface group is a given face (for example "the face at x = 0"), and before any calculix.run_fea or calculix.run_thermal call that has no mesh yet.
