[Gmsh] Onera M6 mesh

[Martin Vymazal]

Hello,

 I'm trying to mesh Onera M6 wing with gmsh. The geometry is defined in a step 
file. I have a hard time meshing correctly the tip of the wing. Even when I 
create a box with specifically small characteristic lenghts around the tip, 
the mesh is still ugly (see attached pictures). I tried to switch from 
MeshAdapt to Delaunay and eventually even to Bamg 2D algo, but it does not 
help (Bamg crashes actually). Is there anything else I could try?

 Thank you.
