Step 2: Add Material Properties
Double-click Engineering Data of Steady-State Thermal. Add Young’s Modulus
of 70 GPa, Poisson’s ratio of 0.3 and Isotropic Instantaneous Coefficient of
Thermal Expansion of 2.2E-5 1/°C to the Properties of Aluminum as shown
below. Close the A2,B2,C2:Engineering Data interface.

Step 3: Set Up Static Structural Analysis
Double-click on the Setup cell of the Static Structural system to launch the
Multiple Systems–Mechanical program. Click Yes on the pop-up window to
read the modified upstream data.

Note an Imported Load item is automatically added to Static Structural (C5)
in the Outline tree. Right-click on Static Structural (C5) and insert a Fixed
Support to the Outline. Apply the fixed support to the bottom face of the heat
sink.
