摘要
By applying a general algorithm to different particle models, i.e. molecular dynamic (MD) and macro-scale pseudo-particle models (MaPPM), two physical phenomena of distinct nature and scale differences, i.e. the mutual diffusion of two gases and the instability on the interface between two fluids, are simulated successfully. It demonstrates the possibility that the general algorithms of good parallelism and software of modular architecture can be established for complex physical systems based on the particle methods (PMs), which will thereby develop into a mainstream approach as finite element (FE) and finite difference (FD) approaches.
