Abstract
This chapter presents the feature-driven method for shape and topology optimization. An efficient and flexible design method is presented by integrating the weighted B-spline FCM and level-set functions for shape optimization. The method is extended to problems where structural supports, i.e., the Dirichlet boundary and free boundaries, are simultaneously optimized. The parametric and implicit methods for shape optimization are unified by employing parametric boundary representation and structural analysis with fixed mesh. The feature-driven topology optimization method is developed by regarding engineering features as basic design primitives and achieving topology variation via the layout and shape optimization of concerned features.
