Constraints

The number of constraints allowed for BEAD_SENSITIVITY is almost as vast as the possibilities for objective function definition. For BEAD_CONTROLLER, the only allowed and required constraint is the BEAD_HEIGHT.

Important:

Only design responses marked with * are also allowed in the controller-based algorithm (BEAD_CONTROLLER).
The Gravity / Inertia design response types are usable only if at least one design response of the other types is used in the objective function or constraints.
Design responses marked with ** are only allowed using Abaqus sensitivities.
*** For the sensitivity algorithm, the same functionality is achieved using DVCON_BEAD instead.
