Part Surface dialog-Part Surface Properties

The Part Surface Properties tab of this dialog is used to specify the part surface properties of the selected elements or regions on a model. Different mesh types have options.

To access this dialog, select the required mesh elements.

Click (Geometry tab > Properties panel > Edit), or right-click and select Properties from the context menu, then select the Part Surface Properties tab.

Dialog element	Mesh type	Explanation
Local heat transfer coefficients		Specifies the heat transfer effectiveness (HTE) criteria to be applied to the selected tetrahedral elements. Use global setting in advanced options Select this option to use the thermal properties specified in the Advanced options of the Process Settings Wizard. Perfect contact When selected, there is no heat resistance between the part and the mold surface. When this option is selected the wall nodes are a fixed thermal boundary for analysis purposes. Local heat transfer coefficients Enables you to specify the heat transfer coefficients for the selected tetrahedral elements. Click Set to adjust or view the Heat Transfer Coefficients for the selected tetrahedra.
Mold surface temperature		The temperature of the mold at the plastic-metal interface, where the plastic touches the mold. In cases where this is an input box, enter the required mold temperature. Note: The temperature of the mold affects the cooling rate of the plastic. The mold temperature cannot be higher than the ejection temperature.
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 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.
Cross-sectional shape		Select the type of cross-sectional shape you want to apply to the selected Midplane element(s).
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: You cannot use occurrence numbers for a Cool, Shrink, Warp or Stress analysis. You must model the part in full.
Exclude from clamp force calculation		If a model contains undercuts, or utilizes slides, the projected area calculation may be over-predicted. This over-prediction causes the clamp force calculation to be overestimated. Use this option to exclude duplicated surface projections from the calculations.
Exclude from warpage calculation		Select this option to exclude selected part surface elements from the warpage calculation.
Name		For ease of identification, allocate a name for the collection of property values defined on the dialog.
