Mesh aggregation support for the 3D residual stress model

The mesh aggregation option for calculating warp, which transforms the original mesh into a coarser one, is now supported for the 3D residual stress model.

The computational time for a warpage analysis is significantly reduced when the Use mesh aggregation option is enabled, while still producing a result close to that of an analysis without mesh aggregation. As a result, the Use mesh aggregation option is on by default.

Note: Molded-in residual stress results are only available when the residual stress model is selected and mesh aggregation is turned off.

Limitations

  • The mesh aggregation option is good for typical thin-walled parts, but is not recommended for chunky parts.
  • It is only supported for the small deflection analysis type (not available for the large deflection or buckling analyses).

Basic workflow to disable this feature:

  1. Click Analysis Wizard, Home tab (Home tab > Molding Process Setup panel > Analysis Sequence) and choose a sequence that includes Warp.
  2. Click (Home tab > Molding Process Setup > Process Settings).
  3. If necessary, click Next until you reach the Warp Settings page.
  4. Set the Warpage analysis type to Small deflection.
  5. Deselect Use mesh aggregation.
