vcvedant is an unknown quantity at this point
Hello everyone,

I want to modify turbulent viscosity for k-epsilon model. I have tried used DEFINE_TURBULENT_VISCOSITY() macro to do so. I get same results using this method when C_MU = 0.09 (default) but when I change C_MU = 0.05 in the UDF, my results don't match those obtained from GUI panel for same value of C_MU. It seems that C_MU value from GUI is not suppressed from UDF.

Does anyone has solution to this problem?
