Elastoplastic finite element analysis on a mimd parallel‐computer

Abstract

This paper presents the development of a parallel finite element algorithm for a MIMD parallel computer. The elements are distributed, onto the processors, in such a way that neighbouring elements are placed onto neighbouring processors. This guarantees a good load‐balancing even in physically non‐linear computations. The distribution of the columns of the global system of equations is done by an election algorithm. For solving the global system of equations we use a parallel preconditioned conjugate gradient solver. Tests were done with an elastoplastic material model for proving the efficiency of assembling and solving the system of equations.
