why would you like to convert hex to tet. FreeCAD FEM has great support for tet meshes, so just use tet meshes.joha2 wrote:bernd wrote:- I would start with export too

thanks for your fast answer!
OS is Linux, distribution: Ubuntu 14.04 type (Lubuntu).
tet/hex question: I think you showed in one of the other threads that it is also possible to generate purely hexaeder meshes with gmsh. As far as I have seen, fenics uses only tet4 elements; is there any helper function in the FEM workbench which converts between the hexaeder and tet meshes?
You need to compile FreeCAD against netget, see topic https://forum.freecadweb.org/viewtopic.php?f=4&t=18967 or use ubuntu daily ppa, or use FreeCAD.FEM GMSH object for meshing.
