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

Hello,

Please give us more info ex. log with error. You can do that by typing:

buoyantSimpleFoam > log.bsfoam
