In this Tutorial is shown how to perform a Restart. Therefore the Advanced User Settings are needed. More information to a Restart here.
Instead of the Design space another volume geometry can be chosen as the Start space. The Design space is still the limit for this optimization. With this option a terminated optimization can be continued or a two-stage optimization with varified optimization parameters can be done.
...
For a Restart a new scenario should be created. With the Advanced User Settings the Start space STL-file can be selected. In this case the exported iteration 22 from an former optimization. Furthermore the symmetry constraints from the first optimization are added.
...
A seconed possibility is to perform a two-stage optimization. Instead of a simple restart with the same optimization parameters the parameters can be verifiedvaried.
Examples:
Skipping the coarse resolution level and caluclate directley on the finest resolution level with an early iteration from a former optimization, if a very fine high-resoltion level is desired
Varify Vary the value for the stress goal to keep the overall geometry with more or less material
Modify an optimization output (remove or add struts) and restart with this modified geometry
Creation of a lattice stucuture of an optimization output and restart to optimize the lattice
