Abstract

Local‐global solution (LOGOS) modes provide a computationally efficient framework for developing fast, direct solution methods for electromagnetic simulations. In this article, we demonstrate that the LOGOS framework yields fast direct solutions for finite element discretizations of the wave equation in two dimensions. For fixed‐frequency applications, numerical examples demonstrate that the memory and CPU complexities of the proposed solver are nearly linear. Β© 2008 Wiley Periodicals, Inc.

## Abstract A sparse direct solver for the electric field integral equation is demonstrated for electromagnetic scattering from perfectly conducting targets of fairly large electrical size. For the geometries considered, numerical experiments demonstrate that both the memory and CPU costs of the re

Investigations of scaling and equilibration of general matrices have been traditionally aimed at the effects on the stability and accuracy of LU factorizations-the so-called scaling problem. Notably, Skeel (1979) concludes that no systematic scaling procedure can be concocted for general matrices ex
