Why do I still have a huge constraint violation percentage even if the output file indicates that the optimization has converged?

    In general, optimization is only considered converged if the constraint violation percentage is zero (or at a very low value). Convergence at huge constraint violations occurs when the given constraints in the design problem are too tight or the design problem is so ill-defined that the design problem cannot be further improved. Thus, the change of design objective falls below the convergence criteria that the user has defined and the optimization process ends.
