Hi Patricia,
the problem is in the .mesh file, all elements are stored as tetrahedrals! Probably, the export of hexahedrals from gmsh to the .mesh format is not correct.

Hi!
I am trying to simulate a hyperelastic 3D cylinder with hexahedral elements. I did the mesh with gmsh and save it as a .mesh file. When I do it with tetrahedral elments everything works perfect, but when I try to simulate the mesh with hexahredal elemnts, SfePy can not read well the mesh and give me this error:
sfepy: warning: bad element orientation, trying to correct...
sfepy: warning: bad element orientation, trying to correct...
RuntimeError: elements cannot be oriented! (0, 3_4)
I've attached the .mesh file with hexahedral elements
Thanks a lot for the help!
