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 this text field like symmetry, intersection and the usage of Start spaces.
The Advanced User Settings can be added to a scenario by selecting the option with a right mouse click.
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 as they are only default settings for the ones described here. The table gives an overview of 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=10" .level_2=10" .level_1=20" .level_0=30" | 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: 10, 10, 20, 30 Default settings filigree: 16, 40, 4, 4 |
Optimizer_stressPercentGoal .level_3=10 .level_2=25 .level_1=50 .level_0=100 | The percentage at which the target stress is reached is set. Default settings normal: 30, 40, 90, 100 Default settings massive: 10, 25, 50, 100 Default settings filigree: 60, 90, 95, 100 |
To set up these additional parameters, the left side of the table needs to be added to the optimization model in the Advanced User Settings Text Field.
In the picture below an example is shown. By adding this advanced user settings, the first (coarse) resolution level will be skipped.
