In native mode you can define the thermal conductivity of a material as a function of temperature. Right-click the
Thermal Conductivity box to select
Function. The
Functions dialog box opens. You can create a new function using the
Function Definition dialog box. The independent variable of the function is temperature.
You can create either a
symbolic or a
table function for thermal conductivity.
For models with materials that have temperature-dependent thermal conductivity you can define steady-state thermal analysis only and not transient thermal analyses. If your model contains materials with temperature-dependent conductivity, then the analysis becomes nonlinear.
