How is temperature calculated in DEFINE_SPECIFIC_HEAT for a material in UDF.
real cp2 = 2000;
*h=cp2*(T-Tref); // How is T called here as we don't define cell and thread inside the macro //
Also since *h is calculated why do i return cp ?

So if Cp function of temperature I can just directly write the equation under DEFINE_SPECIFIC_HEAT and use it for calculation of Cp without assigning a constant value to it ?

Why not use a piecewise linear or polynomial over the UDF?
December 10, 2019 at 4:57 pmDrAmineAnsys EmployeeStick to what rwoolhou suggested. If the function is very complex then udf.

Will try to implement your suggestion.
