Optimal Shape Design using Domain Transformations and Continuous Sensitivity Equation Methods


Abstract

In this paper, we consider two approaches to solving an optimization based design problem where ``shape'' is the design parameter. Both methods use domain transformations to compute gradients. However, they differ in that the second method is based on solving a transformed optimization problem completely in the computational domain. We illustrate the methods using a simple 1D problem and discuss the benefits and drawbacks of each approach.
