You can either create the geometry directly in Apex GenDes or import already existing files. You can import .xb, .step, and .sldprt and .stl files into the program.
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 editor and assign a Material to the design space
The specific values needed are the Young's Modulus (210e3 MPa), poisson ratio (0.3) and density (7.8e-6 kg/mm^3)
...
Nondesign spaces have to be selected using the 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.

Name | Force/Moment/Pressure/Gravity | Direction | Value in N |
|---|---|---|---|
Force - Moment 1 | Force | z | -1000 |
Three constraints are created and attached on the Non Design Regions:
...
The optimization parameters are selected in the Studies Area as well.
Select the Strut Density: Medium (Select the Thickness: Normal)
Select the Shape Quality: Balanced (Select the Calculation Type: Optimizing)
Enter the Maximum Stress: 2 MPa
...
The optimization is finished after 64 iterations (Calculation TypeShape Quality: OptimizingBalanced).
...
Generative Design
You can always change the Strut Density (Design Type), Maximum Stress and Complexity to influence the results and try out different options
The Complexity can be increased for a higher resolution (increased calculation time!)
...
The optimizations below show the influence of the Strut Density (Design Type)when nothing else is changed.
Strut Density: Medium (Design Type: Normal)
...
Strut Density: Dense (Design Type: Filigree)
...
Strut Density: Sparse (Design Type: Massive) → one Fixation was sorted out by the optimization algorithm because it was not necessary to reach the goal of the optimization!
...
The legend can be influenced in different ways. You can add and reduce the steps, enlargen different steps and set new minimum and maximum values. Guidance coming soon!
...
Step 8: Visualization of Displacements
The legend can be influenced in different ways. You can add and reduce the steps, enlargen different steps and set new minimum and maximum values. Guidance coming soon!
