HI,
my question is:

Is it possible to average a variable during a steady state simulation like in a transient calculation? I defined a variable "pressure recovery" and its value is swinging each Iteration. And I need a Expression or something like that, that can average the variable automatically. so i can monitor the value of it during the steady state simulation.
Can someone help me plz. I hope u understand my problem.
thanks

hmm...I would try writing an expression by myself and assigning its value to a variable.
But I don't know if it works in CFX as it would in a regular programming language.
I would try this:
expression ownaverage
sum_pressure_recovery=sum_pressure_recovery+pressu re_recovery
ownave=sum_pressure_recovery/number of iterations

and then create an own variable pressure_recovery_ave wich would be linked to the expression ownaverage

Just a guess...maybe it works...Or others may have an easier solution
