Hello everyone
I used arithmetic average to time average my transient data in CFX. It seemed that it was doing right, and the results were saved in ".trn" format in a directory.
after I opened the CFD-POST to post process my results it showed me all times that I have saved but it seemed the contours were not time averaged, Because in my case which is a bubble column the time averaged results should be like a parabola with maximum point and the air volume fraction should have been focused in the center(5th attachment) but it was not(my result in 4th attachment). I wanted to see if these ".trn" files are time averaged or I should do some thing else and make a setting in CFD Post to get the time averaged results?
I don't know if I'm doing the time averaging process right(1st to 3rd attachments), I once asked here and they said arithmetic average is time averaging, But why it didn't work in my case?
please if any one has any suggestion about this really serious problem help me,
By the way I checked the tutorials and CFX-PRE guide and it didn't give a good explanation about time averaging,
thanks a lot
