I need insert a control on temperature.
This control exist, is real, I have to reproduce it in CFX.
I need to do "Tcontrol (i)- T control (i-1)". How I can do this?
I don't know I can in my time step i, recall Tcontrol (i-1).
How I can write this expression in CEL language?

In CEL you cannot get historical values. This is the single biggest limitation to CEL in my experience. Note functions like areaAve, massAve etc are evaluated from the variables at the previous iteration so if you can get the previous temperature from an areaAve or probe function you might be able to get it working.
