With the Advanced User Settings the optimisation parameters can be influenced even further than the options Strut Density and Shape Quality. Furthermore, a few unsupported options are available using the Advanced User Settings like Restart, Usage of a Startspace, Symmetry and preventing an Intersection.

The appearing text field can be used to add Advanced User Commands to the current Generative Design Scenario.
Restart, Usage of a Startspace & Influencing the Strut Density
To influence the Strut Density even further, changes of the number of iterations, stress goal percentage and number of resolution levels can be made. These settings overwrite the selection of the Strut Densityand the Shape Quality as they are only default settings for the ones described here. The table gives an overview of the default settings:
...
To set up these additional parameters, the Input Commands (left side of the table) need to be added to the optimisation model in the Advanced User Settings Text Field. In the picture below an example is shown. By adding these Advanced User Settings, the first (coarse) resolution level will be skipped and the optimisation starts directly at the second level. You might want to add more iterations to the remaining levels to give the optimisation the chance to reduce the material accordingly. Especially level 2 can use more iterations in this case.

Unterscheidung StartSpace und Restart (Restart mit Restart-file und passendem Befehl)
restart_file=restart_iteration_60.stl | Restarts the optimization at iteration 60 (of course any other iteration can be specified, just adjust the filename) |
Start Space
With the Advanced User Settings a Restart is possible. A Start Space needs to be chosen with which the optimisation will re/start.
...
This way a two-stage optimisation is also possible. For a two-stage optimisation the resolution level and number of iterations must be chosen wisely and will need some fine tuning.
Preventing an Intersection
Intersections between optimisation results and the Design space are needed to create the final, manufacturable design. This ensures all functional sharp edges are available and the generative designed part is inside the boundary limits.
...
If an intersection is not directly requested, the export command “noIntersection” can be added to the Advanced User Settings. In some cases the design space of the optimisation is not the one the intersection should take place with and therefore this additional command can be used. The intersection is not done for the iteration but the result is the smoothed optimisation result. For further information regarding a separate intersection with MSC Apex Generative Design have a look here.
