Hi,

is therer anybody who has a good idea how to generate a time averaged parameter over a given time span?

In a transient model I calculate a parameter depending from veleocities u,w. At the beginning all looks fine. When the flow becomes more and more a stationary state the parameter oscillates around an average level. That's why the convergence drops down. You can see it in the attached figures.

My idea is to generate a time averaged parameter over a given time span, let me say 100s. Is there any good idea?

Best regards
Michael
