Hi, I need to use temperature dependent Cp(specific heat capacity) for my simulation. But in the material properties, the only option I get is "Value". I read the modelling guide and it says that there should be other options as well. Is this some version issue?

Thanks

Can you not set an expression there?

If I recall correctly, the NASA and/or Zero Pressure Polynomials options are ONLY allowed for ideal gas materials.

Is you equation of state Ideal Gar, or constant density material ?

I am using ideal gas but still cannot see the option. Finally I did using expressions. Thanks guys for the help
