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, click the Tetra > Create tool.


    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.

Access
Go to Mesh > Tetra > Create.

Options

Element size definition
The mesh size definition used to create the tetra mesh.
Average size
The average element size used to create the tetra mesh.
Element order
Specify whether or not to create mid-edge nodes.
Maximum size
The maximum element size used to create the tetra mesh.
Retain Existing Surface Mesh
The existing surface mesh is retained.

Layered tetra
Enable layered element generation in close proximity areas.
Number of layers
The number of layers to use.
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.
Fill voids
Fill the innermost cavity while creating the tetra mesh.
Fix mid-nodes for a second order mesh

Restrict minimum size
Restricts the minimum size of the tetra mesh
Minimum size
The minimum size of the tetra mesh.
