"divergence detected in amg solver ads-0" after improving meshing using TUI commands
mesh orthogonal quality reduced after creating inflation on wing surface.
I used inflation on wing surface according to the Y+ values needed for my problem. This reduced my orthogonal quality to order of e-03. I tried to improve the mesh by using TUI commands and then the orthogonal quality improved to e-01. Was happy with the result but, when I initialized the problem it showed this error.

Then i tried with my original mesh and everything was cool. Does this orthogonal quality even matter? only thing i know about orthogonal quality is that it should be close to 1. Any comments are appreciated.
