Hello all!
I am new in using OpenFoam! I prepared a implicite case for rhoPorousSimpleFoam like the tutorial case. But my calculation always stops after few timesteps. From begin I get a "time step continuity error". It stops with "maximum numbers of iterations exceeded" .To prevent this, I reduced the timestep and toyed with the relaxation factors, but all does not help to solve the problem. I have yet solved the problem in a explicite case. This was only possible with very small relaxation factors. But the result doesn't fit well to the calculation with fluent. So I hope to get a better result with a implicite case. My task is to simulate the flux through a catalyst. My mesh has 460000 cells. If you need more information, easily tell me. Thanks in advance!
