Abstract

On the application of a continuous method to 3-D shape sensitivity analysis: a BEM approach for electric design E. Schaeidt, J. Unzueta, A. Longo, J.J. Anza Analysis & Design Department, LA'BEIN, Technological Research Centre, Cuesta de Olabeaga, 16, 4^013 Bilbao, Spain INTRODUCTION This work is motivated by the need to solve shape optimization design problems that arise in some industrial applications, particularly in electric and magnetic design. Modern electrical plants and machinery have to be designed to operate at minimum cost, optimum performance and high reliability grade. These strict requirements need an accurate prediction of the performance at the design stage. For example, some of these devices have to satisfy, at the same time, very strict criteria on electromagnetical performance while occupying as little as possible. The shape optimization problem for such a device consists in finding a geometry which minimizes a given functional (such as the volume) and yet simu
