The Part Surface Properties tab of this dialog is used to specify the part surface properties of the selected elements or regions of type Part surface (Dual Domain) on a Dual Domain model.
To access this dialog, select the triangle elements in a Dual Domain mesh, click
(), or right-click and select
Properties from the context menu, then select the
Part Surface Properties tab.
The collection of property values defined on the dialog are saved to a property set with the description shown in the Name box. In addition, you may be given the option to also apply the property values to related entities in the model.
Dialog elements
| Widget | Explanation |
|---|---|
| Thickness |
Specifies how the thickness of the selected element(s) in the Dual Domain mesh is to be determined. The following options are available: Auto-determine The analysis establishes the thickness of the element by measuring the gap between the two adjacent Dual Domain mesh skins. Specified The analysis uses the specified thickness. This allows you to vary the thickness values for a Dual Domain mesh without having to modify the part in your CAD system and then re-import and mesh the part. |
| Dual Domain Type |
Specifies how the Dual Domain mesh match classification for the selected element(s) in the Dual Domain mesh is to be determined. The following options are available: Auto-determine If this option is selected, the solver automatically classifies the element as "matched", "edge" or "unmatched". Specified Select this option to manually assign a mesh match classification of "edge" or "unmatched" in cases where the automatic classification gives the wrong result, as shown in the Dual Domain Mesh Match diagnostic plot. |
| Occurrence number |
Occurrence numbers are used to specify the number of times that a given flow path is repeated in a model. Enter the required occurrence number. Note: If you intend to proceed with a Cool, Shrink, Warp or Stress analysis, you cannot use occurrence numbers. You must model the part in full.
|
| Exclude from clamp force calculation |
Select this option if you want to exclude the selected part surface elements from the clamp force calculation.
Note: This is useful if a model contains undercuts or will be utilizing slides, as the projected area calculation may be over-predicted. The analysis log will show a double projection of surfaces to the parting plane for these regions. This is due to the way that the projected area of the mesh to the X-Y plane in both Dual Domain and Midplane models is calculated. This over-prediction will cause the clamp force calculation to be overestimated.
