Abstract

An object oriented finite element program is parallelized using OOPAR, an object oriented environment for parallel computing. Within the framework presented, the finite element meshes corresponding to subdomains of the complete domain are read by the individual nodes. The submeshes communicate between themselves to identify neighbouring nodes and an iterative conjugate gradient method solves the global system of equations. No single processor needs to allocate memory for the global grid, nor is there any need to even allocate a solution or residual vector of global size. The issuing algorithm is therefore suited for solving very large problems on a large number of nodes, where none of the nodes is capable of holding the global mesh and/or solution.
