Default rng model &standard k-e model
Posts: n/a
Dear all, I simulated the outdoor airflow for a simple case. The covergence could be easily reached by using standard k-e model. However, with the same mesh, cas file but using rng modelwith wall function. I cannot make it converged for the epsilon.

Is there some thing important to using rng model? could you give me some suggestions on using this turbulence model? how to make it converged?
