Impossible reach the convergence -- CFD Online Discussion Forums

AntonioDesah Member Antonio Join Date: Nov 2016 Posts: 36 Rep Power: 9	Hi all, I am trying to analyze the flow over an airfoil in a 2D model. The velocity is 100m/s. I have chosen transient time and a SST k-omega model. I gave a time step of 0.5 seconds but I am not able to reach the convergence. Actually the model diverges on x component of the moment. I checked the boundary conditions and the mesh. The first ones are fine whilst the mesh is poor but I don't know why since I followed a tutorial precisely. Do you have any solution? I do appreciate your help. Thank you very much Last edited by AntonioDesah; January 8, 2017 at 12:24.
