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.
Name | Young’s Modulus | Poisson ratio | Density | Tension strength |
|---|---|---|---|---|
Steel | 192.000 MPa | 0,3 | 7,97 g/cm³ | 515 MPa |
Aluminium | 72.000 MPa | 0,34 | 2,7 g/cm³ | 200 MPa |
PA12 | 1.700 MPa | 0,39 | 0,9 g/cm³ | 42 MPa |

Step 3: Definition of boundary conditions
...
In this case one force and one moment are applied to the electric motor:
Name | Force/Moment/Pressure/Gravity | Direction | Value |
|---|---|---|---|
Force-Moment1 | Moment | My | 15 kNmm |
Force-Moment2 | Force | x | -3 kN |
...
Four constraints are created and attached on the four inner surfaces of the holes at the outer attachment points:
Name | Direction |
|---|---|
Constraint 1 | x, y, z (=0) |
Constraint 2 | x, y, z (=0) |
Constraint 3 | x, y, z (=0) |
Constraint 4 | x, y, z (=0) |
...
Step 4: Interface Creation
...
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.
