I answer to myself so this can be useful for other users.
I finally could mesh my 3D wing. I summarize what I have corrected in my 
geo file:

   - No nodes selected in the BL field >>> "Field[1].NodesList =" sentence 
   deleted.
   - In "Field[1].EdgesList =" i have chosen those edges which were the 
   intersection between the wing surface and the box wall. 
   - In "Field[1].FacesList" I have chosen all surfaces belonging to the 
   wing.
   - I don't know yet the meaning of "Field[1].IntersectMetrics" but I set 
   it to 1. >> Field[1].IntersectMetrics = 1;

I attach the geo and step file and a picture of my mesh.

Regards,
