i should simulate a rotating disk in fluent, but i don't have any informtion about this issue. i just have the gambit output which is a meshed disk. can anyone help me how i should simulate the rotating disk and where i should enter the rpm of the disk?(i don't have access to fluent help)

Hi; You should use a rotating reference frame. At the boundary condition, you should set a rotating domain at the FLUID zone. At this part, the rpm will be asked.

Anyway, I think that you can not peeform a successful simulation without FLUENT documentation. I strongly recommend you to try to provide this documentation.

Hi you could use axiysemetric swril model in fluent and set wall boundary condition with swril speed. sincerely Pourak
