Dear Getfem-users,
I have a problem with computing the outer faces when using a mixed mesh
(having tetras, hexa, prisms and pyramids).
The error is:
face_left = m.outer_faces_with_direction([0, 0., -1.0], 0.01)
File "/usr/local/lib/python2.7/dist-packages/getfem/getfem.py", line
1372, in outer_faces_with_direction
return self.get("outer_faces_with_direction", v, angle, CVIDs)
File "/usr/local/lib/python2.7/dist-packages/getfem/getfem.py", line
1152, in get
return getfem('mesh_get',self.id, *args)
RuntimeError: (Getfem::InterfaceError) -- Error in
bgeot_geometric_trans.cc, line 381 const base_matrix&
bgeot::geotrans_interpolation_context::B() const:
Non invertible matrix
Please let me know if you have any idea. Thank you.
Best regards,
Phuoc
