ThermalMaterialAssignment Properties

Thermal material properties assignments

A ThermalMaterialAssignment object contains the description of a thermal model’s material properties. A ThermalModel container has a vector of ThermalMaterialAssignment objects in its MaterialProperties.MaterialAssignments property.

Create material properties assignments for your thermal model using the thermalProperties function.

Properties

RegionType — Region type

'Face' | 'Cell'

Region type, returned as 'Face' for a 2-D region, or 'Cell' for a 3-D region.

Data Types: char | string

RegionID — Region ID

vector of positive integers

Region ID, returned as a vector of positive integers. To determine which ID corresponds to which portion of the geometry, use the pdegplot function. Set the 'FaceLabels' name-value pair to 'on'.

Data Types: double

ThermalConductivity — Thermal conductivity of the material

nonnegative number | function handle

Thermal conductivity of the material, returned as a nonnegative number or a function handle.

Data Types: double | function_handle

MassDensity — Mass density of the material

nonnegative number | function handle

Mass density of the material, returned as a nonnegative number or a function handle.

Data Types: double | function_handle

SpecificHeat — Specific heat of the material

nonnegative number | function handle

Specific heat of the material, returned as a nonnegative number or a function handle.

Data Types: double | function_handle

Tips

• When there are multiple assignments to the same geometric region, the toolbox uses the last applied setting.

• To avoid assigning material properties to a wrong region, ensure that you are using the correct geometric region IDs by plotting and visually inspecting the geometry.
