I have been trying to simulate flow conditions on a 3D wing. Its successful with unstructured mesh (to a large extent) but when i try the same with structured mesh, the flow is diverging immediately after a few tens of iterations. I eliminated almost all sudden variations in grid size as much as possible and it still exists.. As of now i am completely out of ideas. So pls kindly pour in as many suggestions as possible.

I have uploaded the .tin and .blk files for you to check the mesh. In case of contours from fluent, pls mention the one you require and i will post it immediately.
The below link contains the mesh files..
