How to have more orthogonality.....
 

Hi,
i have a problem with my study. The problem is to make mesh more orthogonally at the trailing
and leading edge i'm premeshing the shown airfoil (Eppler 61) but whatever i've done
it did'nt fix it. I've tried changing the mesh topology, using Orthogonality option in Smooth
method's menu. I'have also tried creating a split in my O-grid block and then using
the match edge's option in meshing parameters but i hadn't found the right solution.
Could anybody help me? Where can i find a tutorial or an example to see a way to fix my problem?
Thanks
