Hi everyone,

I am carrying out an analysis of flow over a half wing. I am doing it for different aspect ratios. However, what is happening is that when I use a particular set of settings for the mesh for cases with higher aspect ratio, I am getting a converged solution, but when I reduce the aspect ratio of the wing, the solution diverges.

Why could this be happening? I reduced the mesh size as well but that is not working. Otherwise modelling of the physics is to remain the same, right?

Thanks in advance,
Rachit
