Here is the case:


Im simulating filter press chamber. The real situation is there is one inlet and two outlets, one of which the filter membrane (porous medium).



I had good convergence when setting the inlet and two outlet as boundary conditions without the porous resistance. Same happend when i set the resistance-free outlet as a wall and the porous outlet as porous jump. Both i did as a test.



What can i do about it? The mesh is fairly good: 300k volumes and 0,2 minimum orthogonality
