Use GCMMA

Choose globally convergent MMA updates rather than the standard MMA variant.

Where to find it

System Solver → Optimization → GCMMA/MMA → Use GCMMA

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

true.

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.
