Define the Material Properties

1. In the Model tree, right-click on Materials and choose New.
2. Change the Name to 4130 Alloy Steel.
3. Make sure Thermal is selected, then enter 40.53 for C (Specific Heat) and 0.00055555 for K (Thermal Conductivity).
4. Then under General enter 150 for T_REF (Reference Temperature).
5. Under Structural, enter the properties shown in the image below. They will be used in the Linear Static Thermal Stress Analysis.

   

6. Click OK.

With heat transfer analysis, the important material properties (thermal conductivity and specific heat) can be input under the Thermal section. The mass density () can be input under the General section. And there is no need to input any structural properties.
