Core algorithms and key software development issues of smoothed particle hydrodynamics

LIU Moubin,SHAO Jiaru(Institute of Mechanics,Chinese Academy of Sciences,Beijing 100190,China)  
As the software development of Smoothed Particle Hydrodynamics(SPH) is relatively backwards due to many unresolved key issues,some key numerical aspects of SPH including accuracy,approximate discretization scheme of particle,particle distribution and size,adaptation of deformation,adaptation of time step,boundary algorithm and coupling algorithm are discussed.The core algorithm and some key issues in SPH software development are also analyzed,which include high performance computation and parallel implementation,pre-processing and particle generation,post-processing and visualization,and so on.Several feasible solution are proposed for different problems to provide some references for the SPH software development.
