general tips on improving mesh quality?
 

All the information ive found on improving mesh quality on not complex geometries is basically the same: use proper sizing and inflation where it is required.

Ive done that and my mesh quality paremeters are all in the "acceptable" range. Despite that, i need to keep improving them due to simulation/convergence problems.

Basically i reached a point where improving my sizing and inflation settings does nothing to my mesh quality, so i ask: what other factors/settings can i modify to improve quality? (hex method its not compatible with my model btw)
