Abstract

A two-dimensional electromagnetic (EM) finite element analysis code which runs on the JPL/Caltech Mark IIIfp Hypercube is being upgraded to handle fully three-dimensional scattering problems. The EM code uses finite elements to model a finite problem domain which may include regions of anisotropic or nonuniform dielectric properties. It solves the single-frequency source driven vector wave equation for electric or magnetic fields in this domain. The code is being implemented as a testbed for finite elements as applied to EM problems, with several types of elements, radiation boundary condition strategies, and parallel solvers.<>
