Average of Expressions in Transient Run for Parameter Study
Join Date: Jan 2012

I am currently working in Workbench and am setting up a parameter study with my own custom expressions being used for inlet and outlet parameters. I am able to obtain data and create the graph in Workbench when varying an inlet condition in a steady state run as it takes the final value of each outlet parameters.
However, I am looking to use the same procedure for a transient run. This is clearly more difficult as my output expressions are more or less sinusoidal. Is there any way of taking an average of the output parameter expressions over the simulation timesteps (even better, the last 25% of them) in the transient run in order to create the automated tables and graphs in workbench?
Any info would be great. Cheers.

Yes, what you are looking for is possible. It has to be set in CFX-PRE.
In CFX-Pre, under "output control tab", you can find "Trn Stats" and under that option, you can find the average option for variables.
And if you would like to have an average value of a particle variable at a particular location, you need to create an expression and a variable. For ex. to obtain an avergae value of torque of a blade, the following steps have to be followed:
