You'll get this: 2948 Changing the velocity vector works for low AoA, but I don't think it's a good idea for high AoA. Your grid wouldn't be...

At that point, I don't think it can be solved as a steady problem anymore. However, you'll still want to stretch the grid. How are you setting the AoA?...

The point is to stretch it so that the waves you are trying to push out of the domain become unresolved near the boundary. This will cause them to...

You should move your boundaries out, like DoHander said, and also make sure your really stretch the grid as you move out to the far-field....
