This work proposes an improved mesh partitioning approach and employs the multi-level substructure method to successfully further improve the efficiency of the parallel substructure method for nonlinear dynamic finite element analysis. A parallel equation solver approach for parallel finite element analysis using SPOOLES is employed and is numerically compared with the parallel substructure method. In addition, the PC cluster is enhanced by adding a jobbatching system. This improvement allows multiple users to run their parallel programs without interfering each other. |
