Move limit

Limit the size of a design-variable change during an optimization update.

Where to find it

System Solver → Optimization → GCMMA/MMA → Move limit

How to use it

First solve the starting design. Change this control deliberately and compare convergence, evaluations and feasibility with the previous run.

Initial value

0.1.

Result

Compare the final objective, constraint values, design and termination reason together.

Troubleshooting

Limits on iterations or evaluations can end a search before an optimum is reached. Inspect feasibility and termination reason, then verify the final design with a solve.
