为了用离散元法（DEM）得到定量可靠的结果，越来越需要精确地再现不规则颗粒的形状。提出了一种简单、快速的球体拼接生成复杂形状的方法。本文展示了它的能力，再现的形状，其分辨率和所需的球体的数量。
In order to get quantitatively reliable results with the discrete element method, or DEM, it becomes more and more necessary to reproduce accurately the shape of irregular particles. A simple and fast original method to create complex shapes by assembling spheres together is proposed. This paper shows its ability to reproduce a shape, its degree of resolution and the number of spheres required.
