I'm using the k-omega sst model and the quick scheme for all equations (I found this in an article). Re is about 7200. I did three meshes of 12000, 32000 and 90000 elements. I cannot achieve the convergence using the quick scheme for the momentum equation. I already tried modifying the under-relaxation factors. Could you tell me how can I reach convergence using quick scheme for momentum equation? __________________ Silvia Best Regards Last edited by Silvia CT; March 1, 2014 at 01:14.
