Part (3D) dialog-Part Surface Properties

The Part Surface Properties tab of this dialog is used to specify the properties of the selected elements.

To access this dialog, select the tetrahedral elements in a 3D mesh, click (Geometry tab > Properties panel > Edit), or right-click and select Properties from the context menu, then select the Part Surface Properties tab.

The collection of property values defined by 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.

Note: 3D-Cool analysis does not support the use of occurrence numbers.

Dialog elements

Widget	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: Use this option if you want to use the thermal properties specified in the Advanced options of the Process Settings Wizard. Note: To view the global settings, Click (Home tab > Molding Process Setup panel > Process Settings). Click Advanced options. In the Solver parameters group, click Edit. Select the Mesh tab. 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: Allows 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.
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.
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. This over-prediction will cause the clamp force calculation to be overestimated.
Exclude from warpage calculation	Select this option if you want to exclude the selected part surface elements from the warpage calculation.
