Hello,
I am doing a tutorial of multi-rotating frame in ANSYS FLUENT in which i have rotating zone of blades and a stationary zone for incoming fluid. I followed the tutorial of multi-rotating frame but I am not satisfied. Since upon giving the moving zone the rotational velocity to moving zone, the wall are still at the same position. I know if I want to move them I will be needing dynamic meshing, what in the tutorial they are trying to simulate? The tutorial is of centrifugal pump.
