| Abstract: | The parallel Boundary Element Method(BEM)for elasto-static problems on cluster was studied and applied.The node-super-row cycle storage was used to implement the parallel formation of BE equations and load balance.A parallel Gauss-Jordan elimination of BE equations was presented based on node-super-row cycle storage.To solve the arbitrary sub-domain partition problems,the parallel condensation and elimination sub-domain by sub-domain were used based on the node-super-row cycle storage.The programs of these ... |
