July 19, 2017, 09:46	Modify turbulent viscosity using UDF	#1
vcvedant Member Vedamt Chittlangia Join Date: Feb 2016 Posts: 64 Rep Power: 9	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?
