Hello all, First of all tha
 
Hello all,

First of all thank you very much for this great software!
Does someone know if there is a k-omega-model available in OpenFoam?
I need this model to simulate a hard wall as a turbulent viscosity model.

Any help is appreciated.

Hi daniel

did you take a look in the file turbulenceProperties under /constant directory

i was not able to see k-omega in that

Hello Kumar, thank you for
 
Hello Kumar,

thank you for the quick reply.
Yes I had a look in this file before posting this thread. The problem is, there is only a simple k-Epsilon model available, but I need the k-omega model instead because it`s better when simulating a hard wall turbulence situation.
But I also tried to use the LaunderGibsonRSTM but I have to figure out first which config files (k,epsilon, R) are exactly neccessary when using LaunderGibsonRSTM.

Could someone give me hint?

Hi Daniel Please look in /O
 
Hi Daniel

Please look in /OpenFOAM-1.2/src/turbulenceModels/incompressible/LaunderGibsonRSTM ( or have you already done this ?? ).

looks like the model needs all the 3!
