Good evening, Having just installed getfem with python interface, I tried to run the demo python files and I am facing divergence problems for the two following files : demo_wheel_contact.py and demo_tripod.py.
·
For demo_wheel_contact, the output ends with Level 1 Warning in getfem_superlu.cc, line 217: SuperLU solve failed: info =7401 Singular tangent matrix: perturbation of the state vector Singular tangent matrix: perturbation failed, aborting. ('alpha_D = ', -1.7013307862685368e-50) ·
For demo_tripod, I obtain: Level 2 Warning in ../../src/gmm/gmm_precond_ilu.h, line 182: pivot 404 is too small Level 2 Warning in ../../src/getfem/getfem_model_solvers.h, line 105: gmres did not converge! To be noticed, the tests with make test have passed. If you have an idea of a way to solve it, could you please let me know ?
