Restrictions in bead optimization can either be defined as boundary conditions that limit the node displacement or as a LINK-condition. The latter is only allowed for controller-based bead optimization. A design variable constraint is a restriction that directly affects the individual design variables or the individual design nodes. Possible restrictions are:
It is also possible to influence the allowable displacement direction by limiting the displacement to specific coordinate directions. In addition, it is possible to link the design variables and to force them to be optimized in a symmetric way (only controller). The definition of the design variable constraints for bead optimization is done using the DVCON_BEAD command.
Restrictions for Bead OptimizationThe following individual restrictions can be defined for bead optimization:
