Hello, 

For a mixing tank, you can simply switch from an MRF to a Sliding Mesh by checking the 'Mesh Motion' option instead of the 'Frame Motion' option. If you want to account for the physical rotation of the impeller, this will be the best approach as the setup for both approaches (MRF and sliding mesh) are identical. Dynamic mesh might be an overkill for this type of a simulation since the mesh is not deforming.

Best,
