CFD Post Expression: How to calc a value at a time step?
 

Hello CFD Community,

I have a transient calculation of laminar flow through a simple pipe which is periodical heated.

Now I want to know the following:

areaAve(Temperature)@OutletPlane "at Time = 0.20 [s]"

The left side of the expression (areaAve(Temperature)@OutletPlane) works well but how to write an expression to get the average temperature at the OutletPlan "at the time 0.20 s"?

I need this value as output parameter for a "response surface optimization".

Thanks for any help!
