UDF of Turbulent viscosity
 
Hello, friends,

I just wonder if we need to write UDF of turbulent viscosity in viscous model(except RSM model) when you don't have special requirement on it. I try the non UDF condition and another one employed the UDF as the normal: mu_t = Cmu*rho * SQR (k)/eps, but the result looks the same.

So I need your correct answer.

Many thanks Justin
