I am refining a rectangular grid a couple of times using the function "operations -> refine cells and faces factor 2".
Unfortunately, the final mesh has quite some many triangles with insufficient orthogonality.
I tried now to re-fine the grid in various ways, but the issue remains.
Is there a way to change the orthogonality a posteriori, i.e. in the already refined grid?
Or what's the trick to avoid this issue?
Thanks a lot!
