Hello Federico,

Thank you for your answer. The top figure is a cut with the plane z = 0. The domain is extruded in both directions (from z=-c/4 to z=c/4, where c is the chord of the main wing element), and a periodic boundary condition is defined in both surfaces (z=-c/4 and z=c/4). I have done this directly in Fluent Meshing, so that the mesh coincides in both surfaces.

Regarding the other extensions, the bottom figure shows them. The inlet is approximately located 10c away from the wing, the outlet 20c away from the wing, and the slip walls 10c away from the wing.
