Abstract: A parallel three-dimensional smoothed particle hydrodynamics cede CSPH3D based on MPI is introduced, including computational scheme, parallel method, data structure, flow chart, and skills in programming. A simulation of three-dimensional ejection and penetration model shows that the CSPH3D code preferably simulates these phenomenon and the parallel efficiency is high. The parallel efficiency of a 1527402 particles micro-ejection model and a 1454225 particles penetration model achieves 80% with 100 processors.

Key words: smoothed particles hydrodynamics, parallel computation, penetration, micro-ejection
