Abstract
There are two distinct approaches to shape optimal design - the geometric approach where the design variables are geometric-related quantities such as coordinates of nodes, coefficients of polynomials or splines etc. and the natural approach where the deformation field produced by fictitious loads and specified displacements, is used for the shape and mesh updates. Both these approaches have their strengths and weaknesses. This paper presents the characteristics of these approaches, compares their performances and presents numerical examples that have been solved using both approaches.
