I have a case that I ran with simpleFoam. The results were not great, so I tried changing the refinementSurfaces levels from (5 5) to (6 8) in snappyHexMesh. The new mesh did not show any problems in checkMesh, but when I ran simpleFoam again, it diverged in 60 steps. Any suggestions?

I have 2-D airfoil at low speed, so incompressible. I am using OF 2006.

My case files are too big, even compressed and leaving out the polyMesh files, so I am attaching what seem to be the most relevant.
