Study on parallel algorithm of Eulerian method for three-dimensional multi-material plastic-elastic hydrokinetics

Parallel computing of 3D explosion and shock processes on the parallel computer is effective means for the large-scale numerical study of explosion and shock process. Considering the complexity of the parallel programming, the overall strategy for parallel programming of 3D mutil-material hydro-elastoplastic hydrocode MMIC-3D was discussed, and the PMMIC-3D parallel hydrocode was designed based on MPI (Message Passing Interface). In addition, a practical plan of program testing was presented. The speedup, efficiency and scalability of the PMMIC-3D parallel hydrocode were tested on the cluster consisting of 8 nodes based on the numerical example of shaped charge jet, and the effect of the bottlenecks of PMMIC-3D parallel hydrocode was discussed.
