I ran a simulation about an agitator (impeller), and came upon a question about rotating zones. When using a rotating zone is applied, does it rotate the object within the zone? Or does it rotate the zone itself (object and liquids). For example, I want a turbine submerged in a volume of water to rotate at 12.6 rad/s. I apply a rotating zone of such velocity. Does that velocity apply ONLY to the turbine, or will it apply to the liquid within the zone as well?
