wake modeling (internal wall, patch dependent)
 
1 Attachment(s)
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, IŽd 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?

Thank you for advice.

I used your tin file and the same curve settings with patch dependent. The only modification I brought is in shell meshing parameters " respect line elements" has been turned on. And the respect line elements criterion was reduced from 0.0001 to 0.00001

and edge criterion in volume meshing reduced from 0.2 to 0.01.

It respects the symmetry plane then. Give it a shot. If you want I will upload images or mesh file later
