Abstract

The boundary integral method is used to solve electromagnetic scattering by perfect electric conducting or dielectric bodies. Due to the memory requirements, the size of computed problems is limited on regular scalar computers. The use of a distributed memory parallel computer allows one to remove this limitation and to solve large problems (dense matrices with more than 100000 rows). The problem assembly is performed by nodal contribution, and the BiCGStab(m) algorithm is used in its solution. This leads to very good parallel performances
