Case diverges systematically after refining grid
I'm experiencing another problem with the same case from which issue #1143 (closed) originated (@kuti).
After refining uniformly the grid generated by snappyHexMesh (by increasing the initial blockMesh resolution) and then extruding the mesh via extrudeMesh, the simulation runs fine in rhoPimpleFoam but diverges systematically in rhoSimpleFoam either in serial or parallel execution, whereas but solvers work fine with the coarser grid resolution.
Not sure if the issue belongs here as it might be a problem with the model setup, but given the former issue with the same case may be worth checking it?
