DESIGN OPTIMIZATION IN ELECTROSTATIC-FIELD ANALYSIS USING THE BEM ANDTHE AUGMENTED LAGRANGIAN METHOD

The aim of this paper is to discuss the reliability of a new algorithm based on the augmented Lagrangian method (ALM) coupled with the bound ary element method (BEM) for design optimization in electromagnetics. These methods, implemented as a computer code, have been applied for t he solution of electrostatic problems. Two analytical problems are con sidered and the convergence of the ALM for different starting points h as been noted. Also, the algorithm is robust with respect to the numbe r of design variables. Moreover, two electrostatic problems have been solved and the efficiency of the ALM coupled with the BEM has been obs erved.
