Ansys is suggesting me do inverse orthogonality quality to improve the meshing. How do i get that? My orthogonality is 0.099 and my skewness is around 0.93 max and 0.2 min. How do i improve the skewness?
I am using tetrahedrons meshing with coarse, curvature, medium for span angle. |

Hi Felix,
Difficult to say without a picture of your domain. But the numbers you mentioned represent a really bad mesh. You should increase the mesh density or use local refinement for problematic areas (with high skewed elements). Play around other mesh option instead of curvature, to proximity, play around with defeaturing options etc. Again a bit difficult to guess without additional pictures/problematic area info. Best of luck

Thanks for the advice. I will try to learn a how to use the refinement. Here is a picture in case some can give more detail feedback.

You should definitively add refinements and inflation option to get your BL right
