RBDO: constraint function is a finite element model

Dear professors:
I have one question: When there is a limit state function in the constraint function that is a result of the finite element model calculations, and I’m going to replace this finite element model with a metamodel. How can I handle this problem in the UQLab uq_constraint?
I hope you can provide me with a solution to this problem.
Thank you very much!

Dear @Mr121Tony

Can you give a little more information about your problem? Do I understand correctly that it is not the limit state function that is constrained but your FEM model?

Best regards

Thank you @styfen.schaer , I have solved this problem.
