Hi,
In the turbFoam.C file under // Momentum predictor there is a line which says: + turbulence->divR(U) What does that mean? Or where can I read about it? It hasn't been possible for me to find it in the OpenFOAM guide. Furthermore there is a minus in front of some equalitysigns. How do I interpret that? I really hope that someone can help me. Regards Lasse |

What you are looking at is the contribution of the turbulence model to the momentum equation, which comes in (its most general) matrix form.
Have a look at the k-epsilon model code to see what's in there, it should be clear (basically a laplacian with nu_t + nu_l). Enjoy, Hrv
