Hi

I want to ad modification to K-epsilon model in CFX 4.4. However, I want to modifey the source term in the dissipation equation. I wanyt to multiply C2 constant by (1-c*RI). c is about 0.2 and Ri is the Richardson number. The Ri is defined as follows:

Ri=(k^2/eps^2)*(u/r^2)*d(ru/z)

I will be happy if any one can inform me how can I modifey this in CFX4.4

Bye
