Step 1: Start MSC Apex Generative Design 2020
The program starts and you can directly create your optimization 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, .xt, .step, and .sldprt files into the program.
...
Nondesign spaceshave to be selected using the Optimization Tools. In this case the top plate is created as a Nondesign space with an offset of 1 mm and the three screw holes are being used with an offset of 3 mm for each.
...
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.
...
Name | Direction |
|---|---|
Constraint 1 | x, y, z (=0) |
Constraint 2 | x, y, z (=0) |
Constraint 3 | x, y, z (=0) |
...
Step 4: Definition of load cases
The next steps are defined in the Studies area.
...
Active in Event1: Force-Moment 1, Constraint 1, Constraint 2 and Constraint 3
...
Step 5: Definition of optimization parameters
The optimization parameters are selected in the Studies Area as well.
...
Don’t forget to save the project!
...
Step 6: Starting the optimization and visualizing the results
If all data is correct, the optimization can be started and tracked in the Post Processing. The Analysis Readiness function checks if all information are provided and the optimization can start.
...
The optimization 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!)
...
Strut Density: Dense
...
Strut Density: Sparse
...
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.
