Convergence status dialog box

A successful optimization is when a converged solution is achieved and a convergence status message is displayed in a dialog box.

If optimization processing does not complete because you cancel the optimization process or if an error message is displayed, all valid iterations that have been completed are saved.

You can use the Control Parameters page in the Optimization dialog box to increase or decrease the number of processing iterations that the simulation is allowed to run.

You can use the Convergence Parameters page in the Optimization dialog box to allow some flexibility in the convergence values found for optimization design variables.

This optimization status	Indicates
Optimization did not converge. You can change the optimization parameters and try again.	No convergence.
Optimization converged because the latest changes in design fall within the convergence criteria.	Small change in design; run converged.
Optimization converged because one or more of the convergence criteria has not been met and no better design can be found that would meet all the criteria.	No better design can be found; run converged.
Optimization converged because maximum number of iterations have been reached. You can change the optimization parameters and try again.	Maximum number of design iterations reached; run converged.
Solve/Mesh/Model failure.	The optimization cannot proceed due to a solve, mesh, or model failure.
