Again, I did not understand what you mean about mesh quality. I know that the mesh jump causes instability in the solution, but I produced both meshes with exactly the same Ratios for the block lines, and also the quality of the second mesh is slightly better than the first mesh, but the second mesh does not converge.

Well, this is very strange




I said

The second mesh does not converge and it progresses slowly due to an error appearing in the solution console. That's why I stopped the solution and I don't know what the result will be.
