For the steady-state heat transfer analysis, only the thermal conductivity was needed. For a transient heat transfer analysis, the mass density and specific heat are also required.
- Click the Material heading for Part 1 in the browser (tree view).
- Hold down the Ctrl key and also click the Material heading for Part 3.
- Right-click one of the selected headings and choose Edit Material.
- Click Edit Properties.
- Type 1.29e-3 in the Mass density field.
- Type 92.35 in the Specific heat field.
- Click OK to accept these properties.
- Click OK to exit the Element Material Selection dialog box.
The material for Part 2 (Silicon, Si) is from the Autodesk Simulation Material Library and already has the mass density and specific heat defined.
