Compression element (3D) dialog - Part Surface Properties tab

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

This dialog lists the property values associated with a specific property set shown in the Name box. You can change the values and save them with a new name.

Note: Compression type molding processes do not support the use of occurrence numbers.

Dialog elements	Comments
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. Note: When assigning the heat transfer coefficient to an in-mold label, it is the ratio of thermal conductivity of label to the thickness of the label.
Mold surface temperature	Specify how the mold surface temperature of a selected area on the surface of the model is defined. Use mold surface temperature in process settings- the value is obtained from the Process Settings Wizard (Home tab Molding Process Setup panel Process Settings), and used throughout the molding cycle. This option is selected by default. Constant - this option allows you to specify a constant temperature for the selected area, which is different from the temperature value that is assigned in the Process Settings Wizard. Profile - this option allows you to define a varying mold surface temperature for the selected area throughout the molding cycle.
