I would assign some rotating regions. I have already done it a lot of times but for this case, it's seem to be impossible. I have no warning messages but the rotating region isn't created. I click on the assignment button but nothing happens.
Can i have some advices?
Thank a lot
Solved! Go to Solution.
The rotating region must be contacting an assigned fluid volume, so apply the fluid materials before setting up your rotating region. One workaround is to select all volumes when you first enter into the materials task and assign air, then go through volume-by-volume and assign the proper materials.
