Dear OpenFoam 1.6 users and experts,
I'm trying to use the LES turbulence model "kOmegaSSTSAS". I noticed some differences between the implemented version and the reference**. The main difference is the SAS source term in the omega equation: in the reference there is a (L/Lvk2)^2 (squared) instead of a simple L/Lvk2 (the coefficients of this term are also different). I'm doing a master thesis in CFD using this model, so I'm aware of how the model works. In the study of this model I discovered that the first version by Menter has a simple L/Lvk2 and later this term has been squared. Underlining that the other coefficients of the implemented model are the same of the reference (except those of the SAS source term), I have two questions:

1) Is the difference I noticed a bug?
2) Is the implemented kOmegaSSTSAS an old version of the model and so it needs to be updated?

Any help would be greatly appreciated!
