problem meshing with low y+

cesco

Hello all, I hope someone of you can help me with this problem, I really don't know wath else I can do.

I have to mesh an area around an airfoil but the first points of the boundary layer must be really close to the airfoil

I solved the problem of the negative volumes that Gambit usually creates when the distances between the vertices are so small, creaing a large number of areas to be mesh around the airfoil.

Now the problem is the zones handedness. Typing /grid/modify-zones/repair-face-handedness I solve the problem but the .cas that I write is not readble again in fluent because f the error:

Cell Centroid is xc -0.041689 yc 1.003255 WARNING: no face with given nodes. Thread 11, cell 24868 Error: Build_Grid: grid error.

The mesh is the result of a tmerge, it will be a moving mesh.

Please help me if yo can. Thank you in advance
