3D mesh around a wing using gambit
 

I am using Gambit for creating 3D mesh round a wing . I need a help for creating this mesh.

I tried many ways to mesh edges , faces and then volumes but this method worked for volumes which does not contain wing. For the volume which contains wing this method fails.

Why it fails I donot know ????!!! I need a help or advice for steps or useful websites?

Great Thanks
