The Heater (3D) dialog is used to set up the simulation of hot runner heating elements. To access this dialog, select a heating element tetra, right click and select Properties from the drop-down menu.
| Dialog element | Explanation |
|---|---|
| Heater control | For the purposes of this simulation, the heater element can be controlled according to a set temperature or a set heat rate, or flux. Select the option which best reflects your real-life mold, and enter appropriate values. |
| Heat specification | Available if you select
Heat option for Heater control.
Select the method of specifying heat: Heat Flux or Heater rating. |
| Constant Flux | Available if you select
Heat Flux for Heat specification. Enter the constant flux value in Wm².
A heat flux sensor measures heat transfer in a single direction, by measuring the temperature gradient between two thermopiles. The heat flux is proportional to the differential voltage registered. Constant flux provides a constant heat transfer. |
| Total heat | Available if you select
Heater rating for Heat specification. Enter a total heat value for the element in kW.
The solver calculates the total surface area of the heater element or heater cartridge. Based on the total surface area and total heat rating it calculates the heat flux on the heater elements. The solver uses that as the flux boundary condition. |
| Name | If you have changed the default settings and would like to apply these settings to other analyses, save the changes to a unique name that you can select in future studies. |
| Apply to all entities that share this property | If you would like to assign these settings to the entire heater element, but have not selected all the heater element tetras, check this option to automatically assign the changes to the entire heater element. |
