I am working on the temperature distribution of a nuclear fuel rod. For uranium dioxide, specific heat changes according to this formula, Cp= 264.256+0.047*T. For Zircaloy-2 specific heat changes according to Cp= 255.66+0.1024*T.
I plan to write UDF for specific heat according to the description of the ANSYS UDF manual. Like for UO2,
real cp = 264.256+0.047*T;
*h = cp*(T-Tref);
I have two solid materials. Then, how can I find and set Tref for each material? In Ansys 'Reference Values' the default Tref is 288.16K.

UDF is not required. Just use temperature dependent cp from built-in formulations.

Hello Dr Amine,
Are you recommending writing a 'piecewise-linear profile' for Cp as my original equation for Cp is linearly temperature dependent?
