You can either create the geometry directly in MSC Apex Generative Design or import already existing files. You can import .xt, .xb, .step, and .sldprt files into the program.

• Import/create the Design Space including the Non-Design Spaces in MSC Apex Generative Design. For this Bracket theDesign Spacewas imported.

• The CAD-file includes several solids. The desired Design Space, as well as the dummy part for an electric motor and the needed screws to connect the parts. The latter ones are the Retained Volumes which will be used later on in the model set up.

• Open the Design Space Tool in the Optimization Tools to select the imported Geometry as the Design Space.

  

• Create the material Steel, PA12 and Aluminium in the Materials editor. Assign PA12 to the Design Space, Aluminium to the electric motor housing and Steel for the screws.

• The specific values needed are the Young's Modulus, Poisson ratio and Density.

• The Tension Strength is the maximum allowable stress for the material.

Step 4: Interface Creation

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.

...

In the next step the interaction between the Retained Volumes and the Design Space is defined. For this the Generative Design Configuration Tool is used. Start the Tool and choose the corresponding objects for each step, then click the MMB. For this configuration, only the Design Space is selected as Initial Design Space and the electric motor and screws as Retained Volumes
