Decimate Mesh

Use the Decimate tool to coarsen mesh based on a defined element size.

1. From the Discrete ribbon, click the Decimate tool.

   
   
   Figure 1.

2. Select surfaces or parts to consider.
3. Enter a size threshold.
   Any input elements that have edge lengths smaller than this size value are decimated.
4. Enter a feature angle constraint.
   Any input elements that have a defined angle less than this value are decimated. For inputs with higher curvature, define a higher angle to loosen the constraint.
5. Click Decimate.
