Hi.
I'm setting up a non newtonian material with a viscosity described by the power law in Fluent. The consistency index has to be k=2*exp(-0.7*T), where T is the temperature.
My problem is that I can only set k equal a constant. Can anybody help me out?

Thanks

You might need to write a UDF for it. It should be simple, though.
