How to integrate a variable in CEL ?

Hi, everyone!
I want to calculate the entropy increase by using stagnation parameters as the references, can I do it in CEL of CFX-POST ?
The formula I use is in this picture below, and "Cp" is determined by "T".

Thanks a lot.

You can use the UserFortran interface for evaluating thermodynamic state points.

Quote:

See Chapter 18, User Fortran, State Point Evaluation
The user state point query function enables the evaluation of thermodynamic properties at a user specified state. This is accomplished by calling the following utility routine from within User Fortran subroutines (User CEL functions or Junction Boxes)
