converge issue with RNG model for bluff body
 

Hi, I am modelling the outdoor airflow around a cubic with RNG model. For other models are quite ok. but I got the problems of converging in k and e (around 2e-3). I used non-structure mesh. How could I deal with this convergence problem? Thank you in advance

Hi Did you try with the under-relaxation coefficients? Solve->Controls->Solution.

Hope this helps.
