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. |
