摘要：

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.
