Thermal Values for Isotropic Properties
Click Thermal to specify the following isotropic material properties:
Specific Heat Capacity—Defines the specific heat of the material. Type a positive value.
Thermal Conductivity—Defines the thermal conductivity of the material. To specify the value of thermal conductivity, you can perform one of the following tasks:
type a constant value
right-click and select Function to define thermal conductivity as a function of temperature
right-click and select Parameter to assign a parameter name.
Return to Isotropic.
