...
The program starts and you can directly create your optimization optimisation model
...
Step 2: Model generation
You can either create the geometry directly in MSC Apex Gennerative Generative Design or import already existing files. You can import .xb, .xt, .step, and .sldprt files into the program.
Import/create the Design spaceincluding theNondesign spacesin MSC Apex Generativ Generative Design 2020 as one solid. For this Jet Engine Bracket the already prepared Design space was imported.
Create the material in the Materials editor and assign it to the Design space
The specific values needed are the Young's Modulus (115e3 MPa), poisson Poisson ratio (0.3) and density (4.40e-6 kg/mm3)
...
Nondesign spaces have to be selected using the Optimization optimisation Tools. In this case the four fixation points and two force application points are selected and a Nondesign spaces with an offset of 3 mm is created for each.
...
Creation of local coordinate systems to apply forces
Because the importet imported Jet Engine Bracket CAD-file is shifted and rotated to the global coordinate system,local coordinate systemscan be used to apply the forces and moments.
...
Force - Moment 3 is also applied on both Nondesing spaces in z-drectiondirection. Now the orientation is referred to the coordinate system 2.
...
Therefore, the Loads & Boundary Condition Tool is needed. Under Displacement Constraints a “clamped” constraint can be chosen, which locks translations in all three directions. On the left side of the Tool the relevant geometry choice can be selected. In this case surfaces are selected to attach the constaints constraints on the Nondesing spaces.
...
Step 4: Definition of load cases
...
For each Force - Moment an Event is created including all four Constraints:
...
Step 5: Definition of
...
optimisation parameters
The optimization optimisation parameters are selected in the Studies Areaas well.
...
Don’t forget to save the project!
...
Step 6: Starting the
...
optimisation and visualize the results
If all data is correct, the optimization optimisation can be started and tracked in the Post Processing. The Analysis Readiness function checks if all information is provided and the optimization optimisation can start.
All result iterations are displayed as soon as they are available. Furthermore, you are able to stop the optimization optimisation in this selection area. However, a Restart is not directly possible.
The optimization optimisation is finished after 64 iterations (Shape Quality: Balanced).
