Hello all,
I'm trying to solve a 3d poisson equation on a mesh generated by gmsh.
I receive this warning (about 100 times, for # = 1 to 100)
Level 2 Warning in ../../src/gmm/gmm_precond_ilu.h, line 182: pivot #
is too small
if I decrease the size of mesh to about 180000 elements, I receive an
answer in some minutes, however I still get the same warning.
first of all, what does this warning mean and how can I prevent it?
second, if I receive this warning can I still trust the result?
Kind Regards,
Nima
