Define Temperature Dependent Properties

Define density, thermal conductivity, and specific heat capacity with respect to temperature.

In the menu bar, click Settings > Material database.
In the dialog, select a material to apply temperature dependent properties.
Density, thermal conductivity, and specific heat capacity allow temperature dependent input via material database.

To add temperature curves, select Add Density-temperature curve, Add thermal conductivity-temperature curve, and/or Add specific heat capacity-temperature curve.

Note: Non-zero values should be set for temperature independent thermal conductivity, specific heat capacity, and density along with temperature dependent properties to complete material definition. The curves are utilized only if the Use temperature dependent properties option is checked in thermal transient setup. Otherwise, the non-zero nominal values are used.

Define the temperature curve(s) in one of the following ways:

Method	Process
Import from CSV	Click Import CSV. In the File browser, select the desired .csv file and click Open.
Create manually	Click Add row. Enter the temperature and relevant property values. At minimum, two points are required.

The results are plotted in the XY graph in the dialog. You can use the scroll wheel to zoom in, the left mouse button to pan, or the Refit button to reset the graph.

CSV File Format

Density-Temperature Curve

CSV Fields: Temperature – Numerical value; Density – Numerical value; Note: Units are based on definition in material database settings.

Specific Heat Capacity – Temperature Curve

CSV Fields: Temperature – Numerical value; Conductivity or thermal-conductivity – Numerical value; Note: Units are based on definition in material database settings.

Example File
Temperature,conductivity: 1.136,238.168; 77.273,243.893

Specific Heat Capacity – Temperature Curve

CSV Fields: Temperature – Numerical value; Capacity or specific-heat-capacity – Numerical value; Note: Units are based on definition in material database settings.
