凸多面体的几何由一组半空间来描述。在离散元法中，这种几何表示被用于多面体粒子的建模。提出了一种粒子接触检测和相互作用力计算的算法。最后，通过对料斗内颗粒流动的模拟，验证了该模型的有效性。
The geometry of convex polyhedra is described by a set of half spaces. This geometry representation is used in the discrete element method to model polyhedral particles. An algorithm for contact detection and the calculation of the interaction forces for these particles is presented. Finally the presented model is exemplified by simulating the particle flow through a hopper.
