|Subject:||[Getfem-users] problem with demo_wheel_contact.py and demo_tripod.py|
|Date:||Wed, 3 Jan 2018 16:38:36 +0000|
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 ?
