Hi,
I am new to OF and want to learn how turbulence models are used in it.

There are tutorials which use k-epsilon and k-omega-sst models.

I want to try other turbulence models like q-zeta model, Spalart-Allmaras model and LES models like Smagorinsky, k-omega-sst-SAS and various other models given in OF.

Are there any tutorials using these models?

I need them to know the input files required to define constants and other inputs to the model.

Thank You

Regards,
Achinta

The model constant can be found in the codes of this models

Hi,
I saw some files in $HOME/OpenFOAM/OpenFOAM-1.6/src/turbulenceModels/incompressible/RAS/qZeta

I am not able to understand which one should be given as input in 0/ folder (initial conditions). I want to know the syntax of the inputs.

Thank You.

Regards,
Achinta

by default the modeling constant do not need to be modified
and it is not put in the 0/ directionary

Hi,
I want to use Lien Cubic K-Epsilon model for incompressible turbulent flow. Which divergence scheme is best for nonlinearStress i.e. div(nonlinearStress)?

Thank You.

Regards,
Achinta
