Convergence problem vs. mesh size

Hi all,
Can anybody advise me with the following problem? I use buoyantSimpleFoam solver for the solution of the flow inside a catalyst. When I use global element size 2 mm the convergence is OK. But when I use finer mesh with the global element size 0.5 mm the solution fails after several steps. I use k-epsilon model for turbulence modeling including the wall functions in the boundary conditions. Thanks Atlan |

Please give us more info ex. log with error. You can do that by typing: Code:
buoyantSimpleFoam > log.bsfoam |
