July 27, 2017, 06:37	Calculate the Turbulence Parameters on the fly via UDF	#1
FFD Member Join Date: Aug 2015 Posts: 30 Rep Power: 11	Hello, I do have a fluid with change a huge change in the viscosity over the simulation temperature. The viscosity will be calculated via an UDF. Now I want to calculate the Tke and Sdr for the K-omega Turbulence model on the fly with an UDF. But I didn't found any way to get the kinematic viscosity from my simulation to calculate my Reynolds number. Instead of calculating my Tke/Sdr with an UDF. Is there a possibility, so Fluent take care of it? I do not have a constant viscosity. thats the problem here. Any suggestions? -FFD
