Transient run: I want to create an expression in CFX-Pre that takes as input the time derivative of temperature. This means that I need to access the temperature time derivative during the run. Any ideas on how to do this?

Yah this is easy to give the expressions in CFX. Its a kind of Function of f(x)=A(x)+B... For that i need some more data of the problem what you are lookinf exactly, so that i can help you out of this problem easily. I have created expressions many times for this type of problems.

Thanks. I want to create an expression that computes the time derivative of temperature at a certain location, during a transient run.
