Meshing > Controlling local mesh density (Mesh Controls)

Mesh control definitions

You can create a Mesh Control definition without assigning the mesh control to any specific geometry. A mesh control definition contains local mesh specifications but is not assigned to any specific geometry. For example, you can use options in the Mesh Control Definition dialog box to create a Fillet mesh control definition that specifies an element size of 5 mm on all fillets that have a radius between 0 and 3 mm and a maximum angle less than 150°. The software stores these definitions in the Mesh Controls node in the Simulation Navigator.

You can use mesh control definitions to create templates that contain the standard mesh requirements for parts comprised of similar geometry or parts of the same class. For example, you can create a template that contains multiple mesh control definitions with the mesh specifications for standard hole or cylinder sizes for your parts. Saving these standard specifications to mesh control definitions can help improve the efficiency of the interactive meshing process, particularly if you tend to work with very similar types of parts.

Mesh control definitions in the Simulation Navigator

The software stores mesh control definitions with other mesh controls in the Simulation Navigator. A special icon appears next to each mesh control definition to indicate that it does not have any assigned geometry, as shown (1) in the graphic below:

Assigning geometry to a mesh control definition

If your model contains mesh control definitions, you can use the Edit option in the right-click menu in the Simulation Navigator to assign geometry to the definition. This converts the mesh control definition to a standard mesh control.

Saving mesh control definitions in a template FEM

After you create mesh control definitions, you can also save them in an empty, template FEM file. A template file functions like a seed part that you can use as a basis for creating, developing, or modeling an item. You can then modify the appropriate .pax file to add the new template to the appropriate tab in the File New dialog box. Any subsequent FEM files that you create from the template will contain the mesh control definitions.
