Override Set

Use the Override Set - Thermal Properties simulation object to override the specific thermal properties of a part in your model. You can override the following thermal properties:

• Thermal conductivity

• Orthotropic thermal conductivity

• Specific heat

• Electrical resistivity

• Emissivity

• Solar absorptivity

Supported variables and functions

The following table lists the independent variables and auto-generated expressions for the Override Set - Thermal Properties quantities that you can define using fields and expressions.
