Dear collegues

I try to mes half-wing with symetry plane. I would like to improve mesh resolution in wake region by adding internal wall (with interface BC). After that, I´d like to extrude layers on both side. I have problem with surface mesh.

When I use patch dependent mesh. The mesh of symmetry plane do not match with mesh of wake plane. Pic1.

When I use patch independent mesh. The mesh of symmetry plane match with mesh of wake plane. But there is problem in trailing edge region. Elements from top and bottom side of wing are collapsed together. Pic2.

Does anybody idea what cause this problems?
