How can I simulate a wheel revolving at an specific speed inside a brick with a velocity inlet with a different speed? I tried with a multiple reference frame but it doesn't account for fluid dynamic interaction between stationary and rotating components. I can't ignore the relative motions of the two zones with respect to each other...

Thank you!

MRF should account for interaction between the components but only at that instantaneous orientation you've modeled. If you need to see the changes as the geometry moves you need to model using the Sliding mesh technique and run an unsteady calculation. The Fluent Users Manual says that the MRF solution can be a good starting point for your unsteady sliding mesh calculation.

Hope this helps, and good luck, Jason
