...
Import/create the Design Spaceincluding theNon-Design Spacesin MSC Apex Generative Design as one solid. For this Jet Engine Bracket the already prepared Design Space was imported.
Open the Optimization Tools to select the imported Geometry as the Design Space
...
Machining Allowances should be applied to every functional surface. Thus, at the end two geometries are created: The Norm-Geometry and the Print-GeometryAdjacent Faces should be selected at once, to create one coherent Machining Allowance. Therefore the automatic execution mode can be turned off.
In this case a value of 1 mm was chosen. How much Machining Allowance is necessary, depends on the dimensions of the part and the manufacturing process/machine.Adjacent Faces should be selected at once, to create one coherent Machining Allowance. Therefore the automatic execution mode can be turned off.
Create the material in the Materials editor and assign it to the Design Space
The specific values needed are the Young's Modulus (116e3 MPa), Poisson ratio (0.26) and Density (4.48e-6 kg/mm3)
...
Because the imported Jet Engine Bracket CAD-file is shifted and rotated to the global coordinate system,local coordinate systemscan be used to apply the forces and moments.
By opening the Coordinate Tools a local coordinate systems can be placed on the bottom plane (coordinate system 1).
...
Therefore, the Loads & Boundary Condition Tool is needed. Under Displacement Constraints a “clamped” constraint can be chosen, which locks translations in all three directions. On the left side of the Tool the relevant geometry choice can be selected. In this case surfaces are selected to attach the constraints on the Non-Design Spaces.

Step 4: Definition of Events (load cases)
The next steps are defined in the Studies area.
...
The optimisation parameters are selected in the Studies Areaas well.
Select the Strut Density: Medium
Select the Shape Quality: Balanced
Set the Complexity Setting: 14
Enter the Stress Goal: 600 MPa
