Create the material in the Materials editor and assign it to the Design Space. In this case the material behaviour is Isotropic.
The specific values needed are the Elastic Modulus (192e3 MPa), Poisson’s Ratio (0.3) and Density (7.97e-6 kg/mm3).
The Tension Strength is the maximum allowable stress for the material and is set to 320 MPa.

The maximum allowable stress is shown (320 MPa) and the calculated Stress Goal (80 MPa). By changing the Failure Definition to Stress Goal, the Stress Goal can be entered manually as well.
Step 7: Starting the optimisation and visualize the results
If all data is correct, the optimisation can be started and tracked in the Post Processing. The Analysis Readiness function checks if all information is provided and the optimisation can start.
All result iterations are displayed as soon as they are available. Furthermore, you are able to stop the optimisation in this selection area. However, a Restart is not directly possible.
The optimisation is finished after 64 iterations (Shape Quality: Balanced).
You can check the status of the optimisation in the GD Status and get more information on Warning and Error messages. This can be done directly in the Post-Processing as well as in the Studies tab for an optimisation that has already run.

Step 8: Visualization of Stresses & Displacements
Inside the Post Processing the von Mises stress and the displacements are visible for all iterations
The Scale can be influenced individually
