simpleFoam kOmegaSST k, w and nut initial and boundary values
 

Hello Everyone,

I am trying to simulate flow over an airfoil using simpleFoam and turbulence model kOmegaSST. I have taken k, w and nut values from http://ichrome.com/blogs/archives/342 and http://www.wolfdynamics.com/tools.html?id=110. But after several iterations, soltion diverges. After changing these values many times, I have obtained a stable solution. My question is; how could we select values of these turbulence parameters.

with all respect...
