But for the convergence difficulties, I recommend you start with a simpler model, maybe a 2-eqn turbulence model and see if that converges. If that is OK then go to RSM with simple default boundary conditions. This way you can tell whether the simulation itself has a problem, it is RSM or is your boundary conditions. Be aware that RSM models are much harder to converge than 2-eqn turbulence models and are very sensitive to mesh quality.
