No convergence with k-omega sst -- CFD Online Discussion Forums

K-epsilon works within 1000 iterations down to 9E-3 for the residuals on the mesh but k-omega sst just diverge. What could be the problem? It is still 1-phase and the wall y+ is below 1. Can someone help me? The mesh has 800k cells. Maybe it need to be finer? best regards Last edited by kannstmasehn; April 5, 2013 at 03:47.
