Define the Material Properties

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.

1. 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.
2. Right-click one of the selected headings and choose Edit Material.
   1. 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.
   2. 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.
