Skip the optimised parameters result if the objective function fails

2 views (last 30 days)
Hi
I am using matlab "isqnonlin" and "gamultiobj" (in two different codes) in matlab to optimise six parameters.
My objective function, is a function that calls ABAQUS and run some finite element models (FEMs) and export the result into matlab and matlab should optimised some coficient.
In some cases, matlab uses some coeficient that when the ABAQUS uses them to export the result, the FEM does not converge and it exists unfinished and matlab exports the results and generates the new optimised parametrs based on those unfinished data, which result in inaccurate optimisation.
My question is:
How can I define a condition that, if the condition was true MATLAB would ignore the esimated paramerts and goes to next iteration and estimates new parametrs?
Thanks

Most optimization solvers have an OuputFcn option that will let you define your own stopping criteria:

If it is a "new challenge", I think you should probably post it as a different question, with a more detailed description.
