Parallel computation of meshless methods for explicit dynamic analysis

A parallel computational implementation of modern meshless methods is prese nted for explicit dynamic analysis. The procedures are demonstrated by appl ication of the Reproducing Kernel Particle Method (RKPM). Aspects of a coar se grain parallel paradigm are detailed for a Lagrangian formulation using model partitioning. Integration points are uniquely defined on separate pro cessors and particle definitions are duplicated, as necessary, so that all support particles for each point are defined locally on the corresponding p rocessor. Several partitioning schemes are considered and a reduced graph-b ased procedure is presented. Partitioning issues are discussed and procedur es to accommodate essential boundary conditions in parallel are presented. Explicit MPI message passing statements are used for all communications amo ng partitions on different processors. The effectiveness of the procedure i s demonstrated by highly deformable inelastic example problems. Copyright ( C) 2000 John Wiley & Sons, Ltd.
