Can same edge act as Inlet and Outlet?
 

Hi,

I'm creating an O-Shaped mesh around an Airfoil. The O shape is 180° Inlet and 180° Outlet. When I change the angle of attack I make the Inlet/Outlet curves rotate concurrently BUT I've fixed the blocks so the Mesh will always be the same but some parts of the edges are supposed to change BC. (See figures for Angle of 0°, 15° and 30°). I've associated the 4 outer edges to both Inlet and Outlet edges (which are on different part). But when I'm setting the Boundary Conditions, the Inlet Curve will 'duplicate' the Outlet curve forming a full circle Inlet... and the Outlet boundary condition won't work.

Am I trying the impossible here? I thought the boundary condition would just apply on the cells/nodes connected to the edges?
