Identifying the problem areas with Mesh Diagnostics tools

Applies to 2017.3 Update and later

Prior to using mesh diagnostic tools, get an overview of your model quality by selecting: Mesh Statistics (Mesh tab > Mesh panel > Mesh Statistics).

Depending on the result of Mesh statistics, use then the relevant diagnostics tools to explore the areas where problems are identified:

Overlap Mesh Diagnostics
Identifies elements that overlap or intersect, and therefore occupy the same space.
Free Edges Mesh Diagnostics
Identifies element edges that are not shared, which may indicate gaps or holes in the mesh.
Aspect Ratio Mesh Diagnostics
Identifies elements that have an aspect ratio above a specified limit. Particularly useful to detect slivers.
Note: Use the Diagnostic Navigator to move from an area of concern to another.
