A Parallel Approach To Solving a 3-D Finite Element Problem on a Distributed Memory MIMD Machine

Abstract

'A three-dimensional nonlinear rigid-viscoplastic metal forming finite element package, ALPID-3D, is being developed io run on distributed-memory MZMD parallel computers. Efficient parallelization of the applicarion requires identification and efficient mapping of the compute intensive part of the finite jlement code on the parallel machine. This primarily includes the generation and solution of finite element matrix governing equations within each nonlinear iteration. The Element By Element Preconditioned Conjugate Gradient (EBE-PCG) method is used for solving the finite element matrix equations. An approach to minimizing the communication overhead during the EBE-PCG iterations and timing results are presented.
