Update
The Advanced User Settings give the possibility to (re-)start an optimisation with a Start Space. With this option already optimised results can be modified, e.g. struts can be added or removed, and this new geometry can be used as the starting point of the optimisation. With this Two-Stage-Optimisation already optimised geometries can be highly influenced and steered in the desired direction.
...
The first step is to export an already existing geometry. The result from the following optimisation was used in this case:
| View file | ||
|---|---|---|
|
The last iteration is selected and exported.
...
In general, every previous iteration can serve as a Start Space as welland can be exported.
...
Step 2: Reimport of the already optimised geometry
...
For the copied Scenario the Advanced User Settings have to be set-up. The path to the modified Start Space has to be selected. Furthermore, the Advanced User Settings are used to adjust the number of iterations for each Resolution Level. In most of the cases a Two-Stage-Optimisation should start directly on the highest Resolution Level or at least on the last two Resolution Levels.
In this case twelve ten iterations on the last Resolution Level are entered. How to adjust the number of iterations for each Resolution Level is explained here.
...
You can check the status of the optimisation in the GD Status and get more information on Warning and Error messages. This can be done directly in the Post-Processing as well as in the Studies tab for an optimisation that has already run.
