hadishamsnia is on a distinguished road
I have simulated a backward facing step flow by Ansys Fluent, but have problem with the output results of k, epsilon, mut, and reynolds stress near the wall in all two equation models. i have used standard wall functions, but the values of for example epsilon become out of range, around even 10000 at the wall adjacent.
