Import/create the Design Space including the Non-Design Spaces in MSC Apex Generative Design. For this Bracket the Design Space was 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. We will use these as The Retained Volumes will be used later on in the optimisation.
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 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.
...
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.
In this case we are applying one force and one moment on are applied to the electric motor:
Name | Force/Moment/Pressure/Gravity | Direction | Value |
|---|---|---|---|
Force-Moment1 | Moment | My | 30 kNmm |
Force-Moment2 | Force | x | -2 kN |
...
Four Interfaces are created on the interfaces between the Design Space and the Motor. Thus we hide Hide the Motor as well as the screws to have a better view. A Non-Design Space Thickness and an Offset Distance of 3 mm and a Machining Allowance of 1 mm is entered. Now select the surface and confirm the selection (MMB).
...
Another four Interfaces are created on the inner surfaces of the fixations. Therefore, a Non-Design Space Thickness of 3 mm, an Offset Distance of 3 mm and a Machining Allowance of 1 mm is entered. Now select the inner surfaces and confirm the selection (MMB).
...
Furthermore, we create two Interfaces are created at the bottom of the Design Space, to ensure that the fixations on the different sites are connected and there is a good interface to place the bracket on the ground. For this we select the two outer surfaces at the bottom are selected and choose a Non-Design Space Thickness of 5 mm is defined.

Step 5: Definition of the Generative Design Configuration
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 we just choose , only the Design Space is selected as the Initial Design Space and the Motor motor and the screws as Retained Volumes.
Note: The prior defined Interfaces are automatically chosen after the selection of the Design Space.
