NACA - Inclined flow / symmetryPlane
 
Hello folks,

i investigate some elementary hydrodynamics using i.e. NACA profiles. The following illustration shows the case in 2D:

As you can see, i use a symmetryPlane to split my bounding domain (BTW: '#' represent on half of an airfoil).
My question/problem:
When i want a specified angle fo attack, what is the direction of the flow on the reflected INLET (domain)? I guess the inclined flow is mirrored, too.
Is there a possibility to maintain the inclined flow direction in case of that (e.g. that only the geometry/mesh will be duplicate, not the physical boundaries, maybe the mirrorMesh utility could help)?

thx,
/Stefan
