You can either create the geometry directly in Apex GenDes or import already existing files. You can import .xb, .step and .stl files into the program.
For this Bookshelf a design space was imported.
Import/create the design space including the nondesign spaces in MSC Apex Generativ Design 2020 as one solid. For this Bookshelf the already prepared design space was imported.
Create the material in the materials Materials editor and assign a Material to the design space
The specific values needed are the Young's Modulus (210e3), poisson ratio (0.3) and density (7.8)
...
Nondesign spaces have to be selected using the optimization tools Optimization Tools. In this case the three screw holes are beeing used and a nondesign space with an offset of 2 mm is created for each.

Step 3: Definition of boundary conditions
Go to the Loads & Boundary Conditions 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 one force is defined (on the upper surface):
Name | Force/Moment/Pressure/Gravity | Direction | Value in N |
|---|---|---|---|
Force - Moment 1 | Force | z | 1000 |
...
Three constraints are created:
Name | Direction |
|---|---|
Constraint 1 | x, y, z (=0) |
Constraint 2 | x, y, z (=0) |
Constraint 3 | x, y, z (=0) |
...
The next steps are defined in the Studies area.
All boundary conditions must be assigned to the specific load cases, which are defined as Events. The number of load cases Events can be changed by adding/deleting Events to the Meshless Generative Design Scenario. The assignment of the boundarie conditions to the Events can be made in the Loads & Constrains Window. The already created loads and constraints that concern the design space are listed in this window and can be activated for each Event individually.
