Abstract
Much of the current research in shape optimization has been directed toward the design of rather simple, two- dimensional problems when applied to automotive body components. A new capability has been developed to add a continuous flange along the edge of a shape optimization model, such that the flange height is a design variable which can be controlled by the optimization program. An interactive graphics- oriented geometric modeling capability is described for the efficient creation of design models. Two design examples are presented which demonstrate the automated flange design capability.
