Applies to: Volumes

Summary: Meshes a 4 "sided" object with hexahedral elements using the standard tetrahedron primitive.

To use a tetprimitive scheme

  1. On the Command Panel, click on Mesh and then Volume.
  2. Click on the Mesh action button.
  3. Enter the appropriate value for Select Volumes. This can also be done using the Pick Widget function.
  4. Select Tetprimitive from the drop-down menu.
  5. Enter the appropriate settings.
  6. Click Apply Scheme.
  7. Click Mesh.

The tetprimitive scheme is used to create a hexahedral mesh in a volume which fits the shape of a tetrahedral primitive. The Tetprimitive scheme assumes that each of the four surfaces have been meshed with the triprimitive, or similar, meshing scheme. If more than four surfaces form the tetrahedron geometry, the surfaces forming a logical side can be combined using the combine option.
