Parallel FEM Simulation of Forging Processes on Workstations and HP/Convex Exemplar

摘要

This paper presents three parallel algorithms for simulation of axisymmetrical metal forging processes. The algorithms are based on the non-overlapping domain decomposition method where a mesh of elements is divided into layers assigned to different processes. Parallel programs implementing these algorithms are written in C using PVM calls. The efficiency of the parallel programs is verified on networked IBM RS/6000, Sun SPARCS tations and HP 9000 workstations as well as on HP/Convex Exemplar SPP1000.
