I have a question about a variation of the mixer2D case, which is part of the icoDyMFoam tutorial.

I would like to simulate the effect of different blade shapes in a water pump. So I modified the mixer2D case, added a channel with an inlet at one side of the mixer casing and another channel with an outlet at the opposite side.

Now the inner rotating part moves the sliding interface, so that part of the interface acts like an inlet, and another part acts like an outlet between the in/outflow channels and the rotating part, with these roles changing during each cycle.

What are the appropriate boundary conditions, and how can I define them in the dynamicMeshDict?
