For parts that are symmetric about a cylindrical axis, you can match the mesh by using either cyclic mesh matching or the Symmetry feature in the Mechanical application. The following table describes when to use each method:
Table 2: Mesh Matching for Symmetrical Parts
| If you want to... | Do this... |
|---|---|
| Match the mesh, but you do not want to automatically generate solver constraints for periodic mesh | Apply a Cyclic Mesh Match control. |
| Match the mesh, and automatically generate solver constraints for periodic mesh | Define the symmetry in the model by applying the necessary Symmetry regions, Periodic regions, or Cyclic regions. |
When Periodic Region or Cyclic Region objects exist in the Symmetry folder, match face mesh controls will be created internal to the mesher. If the mesher cannot match the mesh on the objects in the Symmetry folder, it will return a failure or informational message.
