摘要：
In this paper, the origin and the development of modeling method are studied based on critical simulation problems. The detailed process and the improvement of major methods are reviewed. The efficiency and the results of simulation are compared by introducing "interference check indicator" and "the shortest path ratio". It is shown that the distributions of concrete aggregate with vertical subsidence are different under gravity, which affects the durability of material and needs to be simulated by corresponding methods. The parameters including density and aspect ratio are important in mesoscopic study and should be adjusted according to practical aggregate. The review of methods can guide the selection of large-scale and high-precision modeling and normalize the results from different methods and parameters, which can simplify the complex analysis significantly. © 2018, Editorial Department of Journal of Tongji University.
