This option relates to the temperature boundary condition for a Fill+Pack analysis.
By default, the Fill+Pack analysis assumes that the mold facing (top) side of the triangular element is at the mold surface temperature value specified in the Fill/Fill+Pack Settings of the Process Settings. This option can be used in combination with the Mold temperature control setting in the Advanced Options to assign a different mold surface temperature to the selected triangular element(s). The following settings are available:
- Top=Cavity
- Select this option if the triangular element is in contact with the cavity. The cavity-side mold temperature value in the Advanced Options will be assigned to the selected element(s) and will override the global mold surface temperature value in the Process Settings.
- Top=Core
- Select this option if the triangular element is in contact with the core. The core-side mold temperature value in the Advanced Options will be assigned to the selected element(s) and will override the global mold surface temperature value in the Process Settings.
- Local mold surface temperatures
- Select this option if you want to assign a mold surface temperature directly to the currently selected element(s). This temperature value will override both the global mold surface temperature value in the Process Settings, and the core-side and cavity-side mold temperature values in the Advanced Options.
Note: To access the Mold temperature control setting referred to above, click Advanced Options on the Fill/Fill+Pack Settings page of the Process Settings Wizard, click the Edit button associated with the Process controller option, then click the Temperature Control tab.
Note: The top and bottom side of each element is defined by its orientation which can be displayed using
