...
Coordinate system 1 is already created and is the Principal Coordinate System.
...
Go to the Loads & Boundary Condition Tool to enter the loads and fixations. Displacements, Forces, Moments, Gravity and Pressure Loads can be applied using different selection options.
...
Interfaces have to be created for every functional surface - so every surface where a boundary condition is applied to. With this Tool an offset to the inside with the input “Non-Design Space Thickness” and an offset to the outside with the input “Machining Allowance” is created. The Offset Distance is expanding the Interface to the set value to create material on front faces.

Step 6: Definition of optimisation parameters and Generative Design Settings
The optimisation parameters are selected in the Studies Area as well.
Manufacturing Method: Generic AM
Failure Criteria: Von Mises
Strut Density: Medium
Shape Quality: Balanced
Complexity Setting: 149
Keep Non-Design Spaces: All Constraints and Interfaces 51-10 6 are deactivated
...

...
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.
...
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 and for every Event
The Scale can be influenced individually
