Specific Heat (Cp) cannot be calculated by UDF???
 

Hi folks!

I need to make the specific heat of a fluid vary with pressure and temperature. I wrote a Udf that returns the correct values of Cp. Unfortunately Fluent (I am using Fluent 6.3) does no allow me to use an UDF hooked to the Materials form. Can someone help me on this. I thought in using an energy source in the domain of the fluid as a way to account for the higher Cp. Anyone has another idea?

Many thanks in advance, Best regards João
