...
Import/create the Design Space including the Interfaces (Non-Design Spaces) in MSC Apex Generative Design as one solid. For this Bridge the already prepared Design Space and Non-Design Spaces were was imported.
The CAD-file includes several solids. Thus, only one solid is supported for an optimisation, with a Boolean operation the solids can be merged to one. Activate Merge Solids as Cells to create partitions which can be used for Non-Design Spaces.
Open the Design Space Tool in the Optimization Tools to select the imported Geometry as the Design Space. Activate the Symmetric Design Constraint and select the XY and YZ planes to set up the symmetric optimisation.
Non-Design Spaces have to be selected using the Non-Design Spaces Tools. Therefore, the Design Space Object can be hidden. In this case the top plate as well as the foot are directly selected as Non-Design Spaces.
...
Create the material in the Materials editor and assign it to the Design Space. In this case the material behaviour is Isotropic.
The specific values needed are the Young's Modulus (192372 MPa), Poisson ratio (0.3) and Density (7.97e-6 kg/mm3).
The Tension Strength is the maximum allowable stress for the material and is set to 320 MPa.
Step 3: Definition of boundary conditions
With the view display controls in the left top corner the Design Space can be activated to visualize the mirrored geometry. Boundary Conditions can be applied only on the Design Space solid and are mirrored as well.
...
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.
...
One Interface is created on the same surface the force is applied to. Therefore, an Non-Design Space Thickness of 1 mm and a Machining Allowance of 1 mm is entered. Now select the surface and confirm the selection (MMB)
One Interface is created on all surfaces, except the top one, of the fixation Non-Design Space. Therefore, an Non-Design Space Thickness of 1mm 5mm and a Machining Allowance of 1mm 2mm is entered. Now select the surfaces and confirm the selection (MMB).

Step 5: Definition of Events (load cases)
...
Manufacturing Method: Generic AM
Failure Criteria: Von Mises
Safety Factor: 6.4 (Stress Goal: 50 MPa)
You can switch between the Safety Factor and Stress Goal in the properties panel by clicking the gear wheel.Strut Density: Medium
Shape Quality: Balanced
