7. High Performance Algorithm and Computing Analysis Software of DEM Based on GPU Parallel Algorithm

Taking the DEM as the main approach, computational granular mechanics has been widely applied in geotechnical engineering, chemical process, geological disaster, mining engineering, marine engineering, agricultural engineering, mechanical engineering, atmospheric science, medical pharmacy, life science and other fields, and obtained many important research results. With the increasing particle types and combination with traditional numerical methods such as computational solid mechanics and computational fluid dynamics, the DEM has been gradually extended to the material damage and fracture, fluid-structure interaction and other fields. Meanwhile, it also provides a powerful approach to solve the granular mechanics problems in the natural ecology, industrial engineering and life sciences. With the development of computational mechanics of granular materials, the corresponding simulation software have been gradually developed and applied to different engineering fields, which have become an effective means to solve the granular materials problems.
