| Abstract: | Domain decomposition for parallel computing was briefly introduced, and the parallel computing process and primary overhead were analyzed, and the algorithm flowchart including contact was drawn. Furthermore, effect of different domain decomposition strategy on automobile crash computing efficiency was presented. At last, scalability of parallel version LS-DYNA3D on different hardware platform was studied. It is a guide for end users in choosing appropriate hardware platform and computing software. |
