Hi
I have been simulating flows of 295.16m/s over an airfoil.
I have been using SA and k-epsilon turbulence models.
Once angle of attack exceeds 5+. convergence does not occur.
I cannot get my head round what has to be done to values in the solution controls section. How can I increase change of convergence?

Thanks for any response
