Hi,

I want to know, if a mesh structure has high aspect ratio (about 1800) but the analysis is converged, is high aspect ratio a problem? Will my results inaccurate?

Thank you!

Yes high aspect ratio cells can still cause problems beyond convergence. Convergence is not a guarantee of accuracy.


But 1800...? Just delete the cell at that point. =)

Thank you for replying.

The cells with high aspect ratio are inside the boundary layer. I don't think it's ok to delete them. And I cannot decrease it without increasing number of cells.
