Hi,

I'm using openFOAM 2.0.1. What do you mean by "checking for grid independence", my omega BC at the wall depends on the first cell so I'm not sure to understand what you mean? My mesh is such...

Hella again,

I followed your advices, and my results are better than before, but I still don't get the right logarithmic slope in the log layer..

Do you have any ideas what could cause this ?

k-omega SST for wall-resolved TBL, problem with log layer.

Hello Foamers,

I'm trying to compute a turbulent flow on a 2-D airfoil usin RANS. I've created my mesh such that the flow is wall resolved (y+ ~ 1 ). I would like to compare different models: the...
