Should the RANS model kOmegaSST be fully resolved at low Re-number? Is it possible to use it with a wall function?

I have read on many other forums that SST is a low Re model and therefore it is made to be fully resolved (with a fine mesh). However, from other sources I have heard that in openFoam it is...

Is it correct to have a courant number more than 1 even if the simulation is stable enough in openFoam?

with kOmegaSST model, I am able to get a pretty robust simulation even when I have a high courant number, I was wondering if that will result in a correct answer. If yes, maybe I can get much...

Should I use a fully resolved LES in a pipe with flow separation using openFOAM?

I have in my Geometry some cavities with almost zero flow. I was wondering if openFoam comes with some embedded LES model that uses RANS in bulk flows and employs LES near the wall. If yes what is...

What boundary conditions should I apply to LES fields in OpenFOAM?

Hi all, So after failing to get satisfying results to my simulation using the RANS model, I decided to switch to LES. As I am expecting some flow separation, after reading some papers, I decided...
