Hi,

I'm trying to model a 2D spinning ellipse. The model I'm using is a rectangle with 0.3m depth acting as "wind tunnel" and an extruded ellipse (separate mesh) with the same depth.

The ellipse is effectively touching both sides of the tunnel, how do I create an interface between the tunnel and the ellipse in order for it to rotate correctly?

So far I've been able to do a transient rotor stator using the 2 sides of the ellipse to effectively rotate the ball but it doesn't seem to effect the air flow at all, creating streamlines simply go through the ellipse model.

how can i tackle this?
