UDF for temperature and shear rate depending viscositiy
 

Hi,

I am pretty new to UDF programming. I would like to define viscosity in terms of temperature and shear rate. The implemented model for non newtonian fluids does not fit the data of my fluid.

Is there a specified macro within FLUENT associated to shear rate? Like C_STRAIN_RATE_MAG(c,t) for the strain rate?

Any help would be much appreciated
