I want to output the time average variables of an unateady simulation. For example, the total simulation steps is 10000, and I want the last 1000 steps time average. So I set "WINDOW_START_ITER = 9000". I think it will begin to statistic after 9000.
Please tell me if my idea is correct? Or is there any way that get the last 1000 steps TAVG variables?

Yes, that is correct. There is a small description of each of the options in the file config_template.cfg
Code:
% Time iteration to start the windowed time average in a direct run
WINDOW_START_ITER = 500

Hi,

Sorry to bother you. I have another question about the time-averaged output. Before the time average duration that I set, the flow.plt file already contained Meanvelocity_X and other time-averaged variables.

So, are they meaningless, or are they also time-averaged variables?

Thanks again.
