Unable to create hex mesh on a wing in ICEM
 

Hello guys, iam trying to create a Hex mesh for my 3d wing which has an inverse zimmerman planform in ICEM, i hace created a C shaped domain.
I created the blocks, split it, associated the edges, gave node spacing and did everything, its getting meshed everywhere except on the wing surface.
Please help me out with this guys, its kinda urgent. I have attached the images below for the referrence.
Thanks.

Have you do the face to selected surface associations? that might resolve the problems.

side note:
I hope that you are using a blunt trailing edge for the wing, as the mesh beside the wing tip will be compressed to oblivion if you use sharp TE.
