Hi all,
I am a student running simulations on a variety of airfoils (2-D), but it seems no matter what airfoil/method I run (through Fluent) I get this same effect. I believe that this has something to do with the meshing of the surface. I have done really fine structured meshes as well as parameterized all the major mesh settings to root out the problem, but can't seem to find a fix yet. If anyone knows how to fix this it would be greatly appreciated as I have been banging my head against a lead wall for two weeks.

I have attached the graphs of cl (blue being the hand adjusted data). Yellow being the ansys cl output.

If there is anything that I can provide to help solve this please let me know.
