Abstract The discrete element method (DEM) is widely used in calculating powder systems. The DEM makes it possible to determine the complicated phenomena related to particle flowability. However, DEM has a fatal problem, which is that the number of calculated particles is restricted due to excessive calculation costs. Consequently, we have developed a large‐scale model of the DEM, which is called the coarse grain model. The coarse grain particle represents a group of the original particles. Ther
In this paper, we describe an industrial application of the discrete element method (DEM). The DEM has been applied to various powder systems thus far and therefore appears to be an established approach. However, it cannot be applied to many industrial systems because of several critical problems such as modeling of large-scale simulations, complexly shaped wall boundaries and free surface fluid flow. To solve these problems, novel models were developed by our group. A coarse-grain DEM model was
