Hello!I'm trying to solve Poisson equation with Sfepy in a very simple domain, but I found some problem:
1) I need triangular mesh on a rectangular/square domain
2) I have null von neumann conditions ( and I omitted them in boundary condition) like in the discussion https://groups.google.com/forum/#!searchin/sfepy-devel/null$20von$20neumann/sfepy-devel/9-cf42ZKsog/8HlNa6DBTOgJ
3)I know that this problem have many convergence problem, in one of this case is the simulation successful? Or I find some error?
I don't know because the simulation is successful but in the postprocessing the result isn't correct
I attach the problem description file too. If you want I would like some advice about my problem
Thank you very much
