Create Tetra Mesh

Use the Tetra: Create tool to create tetra mesh from closed volumes of shell elements, or from solid or closed surface geometry.

  1. From the Mesh ribbon, 3D Mesh tools, click Tetra > Create.


    Figure 1.
  2. Optional: On the guide bar, click to define tetra mesh options.
  3. Select components, solids, or surfaces.
    Use the drop-down menu on the guide bar selector to set the entity type.
  4. Optional: Activate the Anchors selector on the guide bar and select anchor nodes.
  5. Click Mesh.

Fix invalid surface mesh
Fix invalid input surface mesh before tetra mesh creation.
Quality control criteria
The quality control criteria to be used while creating the tetra mesh.
Tetra collapse >
Optimize the tetra elements to have tetra collapse greater than this value.
Cell squish <
Optimize the tetra elements to have cell squish less than this value.
Volume skew <
Optimize the tetra elements to have volume skew less than this value.
