Parallel Finite Element Computation Based on Coarse-Fine Mesh Formulation

A parallel preconditioned conjugate gradient iterative algorithm for finite element problems with coarse-mesh/fine-mesh formulation is presented in this paper. An efficient preconditioner is derived from the multigrid stiffness matrix. The algorithm is implemented on a cluster of workstation. Example of solution of simple linear elastic problem on rectangular grids is presented and parallel performance is discussed.
