Hi,
Im running a 2D airfoil at M=0.8 and Re=6.5E6 and ive noticed that with 40,000 nodes or around there a solution is calculated on the mesh and accuratly but now im running my grid independance study and i tried doubling and tripling my node count and found that the solution diverged. I was wondering why this would be the case that with a higher node count the case would diverge |

maybe your mesh quality get worst....you should see the skewness and try to be below of 0,84
