摘要: DEM has been well established as a powerful numerical technique to study the fundamentals of granular materials. It has limited application in dealing with practical particulate systems which often involve billions of particles. Graphical Processing Units (GPU) offers a solution to this problem. This paper explores GPU-based DEM development, and its performance is assessed under various conditions. For a packing case using 300,000 spheres, it is demonstrated that the speed up ratio (single GPU to single CPU) …
