kOmegaSSTSAS
 
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). Is it a bug? What is the right version?

Any help would be greatly appreciated!
