dT/dy in UDF

Hi
Does anybody know how to obtain the temperature derivative with position
to be used in UDF ?
i want to use this UDF in 2d axisymmetric model.

T gradient in y direction is C_T_G[1]

Hello, I have a question, I did write a UDF for getting dT/d and I plot it (dT/dy vs x) but I get different values when I plot it in fluent and in CFD post. Any idea why is this happening? Which one would be the right one?
