Default Redefining model constants in S-A turbulence

Hi all,

I'm trying to redefine some model constants in the S-A model so that I can solve a problem non-dimensionally.

The model constants in the equations are CB1, CB2, CV1, CW2, CW3, Cprod, sigma, and kappa. I desire to make some modifications to each of these numbers.

Fluent only gives the ability to change the first 7 of these 8, however. How can I change the model's value of kappa? I am trying to use Spalart-Allmaras with strain/vorticity based production.

Thanks in advance, Amit
