Constraints

This section shows you usable constraints for bead optimizations.

The number of constraints allowed for BEAD_SENSITIVITY is almost as vast as the possibilities for object function definition. For BEAD_CONTROLLER the only allowed and necessary constraint is the BEAD_HEIGHT which is not allowed in BEAD_SENSITIVTITY.

Important:

*BEAD_HEIGHT is only allowed in BEAD_CONTROLLER but not in BEAD_SENSITIVITY. For sensitivity algorithm same functionality is achieved using DVCON_BEAD instead.

The Gravity / Inertia design response types are only usable if at least one design response of the other types is used in the objective function or constraints.
