These diagnostic tools are specific to mesh types that include triangular elements.
If no triangular elements are present, the tools will be deactivated. If you have a 3D mesh, and the tools are active, then you have triangular elements too.
Topics in this section
Aspect ratio diagnostic
You can work with mesh aspect ratios in either normalized or standard format.
Overlapping elements diagnostic
Overlapping and intersecting elements must be corrected before running an analysis. This tool can generate a graphical representation of the overlapping and intersecting elements, as well as a text report that lists the number of overlapping and intersecting elements.
Mesh orientation diagnostic
Mesh orientation is used to provide a consistent means of differentiating between the two sides of a two-dimensional, 3-noded element, as used in Midplane and Dual Domain meshes. The simplest convention is to call one side of the element the top, and the other side the bottom.
Centroid closeness diagnostic
When the centroids of two elements are too close together, this indicates that the mesh is not ideal and needs to be fixed.
