Default Calculate the Turbulence Parameters on the fly via UDF

FFD is on a distinguished road
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?
