particular omega residual behavior
Hi,
is there anyone who can help me to understand this particular omega residual behavior? I’ve already seen it in other cases with the same geometry and I think this problem is somehow connected with the volume mesh. Omega residual suddenly goes to 7.9993e-01 even after 1200 iterations and it doesn't move from that value. Let’s say that I’m analyzing a wing in a wind tunnel. I’ve chosen a k-w-SST viscous model with pressure inlet/outlet boundary conditions. The model normally has 5/6 million elements and the mesh is obtained using TGrid. I use FLUENT in parallel mode. The main problem is: is the solution still valid or is it better to throw it away? How can I solve the problem? Thanks for the help.http://photos-d.ak.fbcdn.net/hphotos..._2636235_s.jpg I've just changed the URF from 0.8 (that is 7.9993e-01) to 0.001 and the omga residual is now 9.9991e-04. What does it mean? |
