Fix Mesh Quality of Tessellated Models
Use the Fix tool to improve the quality of an FE (discrete/mesh) model.
-
From the Geometry ribbon, click the
Fix tool.
Figure 1. -
On the guide bar, click
to define the criteria for
quality improvements.
Note:
- All selected cleanup operations are performed in sequence using the same order listed in the options menu.
- If you have a CAD geometry model with mesh and you want to improve its quality, first convert it to an FE model using the Convert tool.

Options
- Degenerated element cleanup
- Remove very high aspect ratio elements. This option will delete degenerate elements and may create free edges.
- Duplicate element cleanup
- Removes duplicate elements from selected surfaces. Duplicate elements can cause issues in volume meshing, so it is better to remove them before volume meshing.
- Aspect ratio cleanup
- Collapses elements greater than the defined aspect ratio. Use this
option to improve quality locally on already meshed surfaces.Note: Using this option on a tessellated model can distort geometry.
- Element height cleanup
- Collapses elements less than the defined height. Use this option to
improve quality locally on already meshed surfaces.Note: Using this option on a tessellated model can distort geometry.
- Intersection cleanup
- Resolves intersections in the model by moving nodes and swapping
edges.
- Per solid fix
- Fixes intersections within solids only, not across the solids. If all solids in the model are not already connected, it is recommended to turn this option on, or else it may distort geometry where solids are intersecting.
- Number of iterations
- Defines how many iterations attempts it will make to fix intersections.
