OpenFOAM tutorial: MRF approach - Simulation of mixing tank
 

Known for its low computational cost and sufficient accuracy, the MRF approach is used for modeling of relative motion between the stationary baffles/internals and the rotating impeller blades. in agitated systems. This approach considers the rotation of wall (impeller) without moving the mesh by making necessary changes in the momentum equation.

I created a video in my Youtube channel explaining how to use the MRF approach for rotation modeling in an agitated tank.

I followed your tutorial for my own case, the only thing I was not able to do is creating the MRF cell zone. Although I followed the tutorial step by step, when I looked into constant/polymesh/cellzone, ideally there should be list of cellzone, in my case it was nothing. Can you help me please?
