UDF for enthalpy in Fluent 6.3.26
 
At low temperature (around 100 K) Cp (specific heat at constant pressure) depends on both pressure & temperature. But, in Fluent 6.3.26 Cp can not be defined as a function of both pressure and temperature. The provision of writing a UDF for Cp is also not there. Naturally, enthalpy calculated at that temperature range are incorrect. Is there any alternative way to get correct value of enthalpy? Is it possible to write a UDF for enthapy? Please help.
