Circumferential Averaging with time-averaged Massflow
 
Hello everyone,

I'm postprocessing the time-averaged solution of a transient run of an axial 2 stage LP Turbine. I want to extract massflow-averaged radial distributions (for example massflow-weighted Hub to Shroud Line for Total Pressure.trnavg).

Problem is though, when I load a results file that contains time-averaged variables, CFD-Post uses the most recent massflow distribution at the current timestep for the circumferential averaging. However, I should use the time-averaged massflow for the circumferential averaging.
Unfortunately I can't change the weighting variable to the time-averaged massflow and you can't overwrite the CFX Variable "Mass Flow" with another (user) variable/expression.

Is there any way to get CFD-Post to use the time-averaged massflow for the circumferential averaging ? Any workaround or experience you guys have with similar studies ?

If I didn't explain myself well enough, feel free to ask and I'll try to make my question more clear.

I'd appreciate any help I can get on that issue.

Thanks in advance !
