Step 1: Start MSC Apex Generative Design 2021

The program starts and you can directly create your optimisation model

Step 2: Model generation

You can either create the geometry directly in MSC Apex Generative Design or import already existing files. You can import .xb, .step, and .sldprt files into the program.

Step 3: Definition of boundary conditions

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.

In this case only one force is defined on the contact plate with the foot:

Name

Force/Moment/Pressure/Gravity

Direction

Value in N

Force-Moment1

Force

y

-1000

One constraint is created and attached on the inner surface of the cylinder:

Name

Direction

Constraint 1

x, y, z (=0)

Step 4: Definition of Events (load cases)

The next steps are defined in the Studies area.

All boundary conditions must be assigned to specific load cases, which are defined as Events. The number of Events can be changed by adding/deleting Eventsto the GD Scenario. The assignment of the boundary conditions to the Eventscan 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 Eventindividually.

  • Active in Event1: Force-Moment 1 and Constraint1

Step 5: Definition of optimisation parameters

The optimisation parameters are selected in the Studies Areaas well.

Don’t forget to save the project!

Step 6: Starting the optimisation and visualizing the results

If all data is correct, the optimisation can be started and tracked in the Post Processing. The Analysis Readiness function checks if all information is provided and the optimisation can start.

All result iterations are displayed as soon as they are available. Furthermore, you are able to stop the optimisation in this selection area. However, a Restart is not directly possible.

The optimisation is finished after 64 iterations (Shape Quality: Balanced).

Generative Design

  • You can always change the Strut Density, Stress Goal and Complexityto influence the results and try out different options

  • The Complexitycan be increased for a higher resolution and more detailed result (increased calculation time!)

  • The Strut Densityinfluences the structures which are formed during optimisation

Step 7: Visualization of Stresses, Displacements & Mass

The legend can be influenced in different ways. You can add and reduce the stress/displacement steps, enlarge different steps and set new minimum and maximum values.

  • The mass of each iteration can be visualized with a diagram

The whole MSC Apex Generative Design project with all results can be downloaded here:
