Hello SfePy,
During the problem solution I got the error:
sfepy: nls: iter: 0, residual: 5.088014e+00 (rel: 1.000000e+00) warning: singular matrix zeroing nan and inf entries... /usr/lib/python2.7/dist-packages/scipy/sparse/linalg/dsolve/umfpack/umfpack.py:556: RuntimeWarning: divide by zero encountered in double_scalars econd = 1.0 / self.info[UMFPACK_RCOND] warning: (almost) singular matrix! (estimated cond. number: inf) sfepy: rezidual: 0.01 [s]
I attached the problem description and the mesh for this problem. What is the reason of the error? May be the mesh is not very detailed?
Sincerely, Alexander Kalinin
