With the Advanced User Settings the optimization 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 Intersection.
The Advanced User Settings can be added to a Scenario by right clicking on this and selecting the option as shown in the picture below.

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 Density and the Shape Quality as they are only default settings for the ones described here. The table gives an overview of the default settings:
Input Commands | Explanation |
|---|---|
UpSampleConfig fOptimizer_switchAddRemove=58 | Starting with iteration 58, elements are either added or removed and only every second iteration is saved. This is important for the iterations near to the end of the optimization. |
iteration .level_3=20" .level_2=20" .level_1=20" .level_0=10" | Specify how many iterations are calculated at which resolution level. Note that convergence should be achieved at each level. Default settings normal: 20, 20, 20, 10 Default settings massive: 16, 40, 4, 4 Default settings filigree: 10, 10, 40, 10 |
Optimizer_stressPercentGoal .level_3=30 .level_2=40 .level_1=90 .level_0=100 | The percentage at which the target stress is reached is set. Default settings normal: 30, 40, 90, 100 Default settings massive: 60, 90, 95, 100 Default settings filigree: 10, 25, 50, 100 |
By default, the The software uses four resolution levels from coarse to fine (level 3: coarse - level 0: fine). More or less resolution levels can be added or removed. The number behind the level indicates the number of iterations calculated on this resolution level. Moreover, the stressPercentGoal for each resolution level can be changed. More information about the stresses and resolution here.
