A Shape Optimization Scheme With Coupling of Parametric and Freeform Shape Evolution
Jie Shen, David Yoon, Nilesh V. Patel · 2004
In this paper we propose a new shape optimization scheme for better geometric design starting from a base polygonal mesh model. The important features of our approach include: 1) surface partitioning scheme for handling large-scale polygonal meshes; 2) coupling of parametric and freeform shape evolution for efficient and effective solutions. 3) an optimization process constrained by constant volume in 3D cases. Numerical experiment indicates the effectiveness of the proposed approach.
