Yes sorry! I've found the error. Since .mesh files saved directly from gmsh can not be used directly as input in sfepy (due to some problems with the file format ), I did an script to rewrite the files, and this script was done for tetrahedral meshes and I forgot to change when reformatting the hexahedral mesh. Now, with this mesh it's works!!
Thanks a lot :-)!

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!
