Abstract

In this paper we present the parallelism facets in the numerical simulation of the distributed-parameter systems using the finite element method. As a parallel implementation of the finite element (FE) programs, the domain decomposition method is the best among three possible decomposition strategies for the parallel solution of partial derivative equations (PDE), namely, operator decomposition, function-space decomposition and domain decomposition. This is one of the motivations to present the inherent parallelism in finite element programs. The principal objective of the paper is to describe some computational aspects for parallel computers in computer-aided design of the electromagnetic devices using the finite element method. For each stage of FE program there is an inherent parallelism of the algorithm that can be exploited on the new architectures.
