• Import/create the Design Space including the Non-Design Spaces in MSC Apex Generative Design. For this Pedal the already prepared Design Space and Non-Design Spaces were imported.

• The CAD-file includes several solids. The file Pedal_body_1 is used to split the upper surface of the pedal to create the area for the load application point. Therefore, open the Split Surface Tool in the Geometry Edit Tools and select the top left surface as the split surface. Now select all curves that separate the surface as in the picture below.

  

• 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 XZ plane to set up the symmetric optimisation.

• If symmetry is activated, the Z-direction (blue) of the symmetry coordinate system is the build direction. The Z-direction shouldn’t be orientated normal to a symmetry plane. Further information regarding build direction and support reduction can be found here.

  

• The other solid of the pedal Pedal_body_1 is no longer needed and can be hidden or even deleted.

• Create the material Steel 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.MP

Step 3: Definition of boundary conditions

...

• One Interfaceis created on the force application surface. 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 Interfaceis created on the inner surfaces of the fixation. Therefore, an Non-Design Space Thickness of 2 mm and a Machining Allowance of 1 mm is entered. Now select the inner surfaces and confirm the selection (MMB). The outer most surface of the Fixation is not selected because is would create material outside of the Design Space.
