“…Then, a sequential sphere packing method was applied to establish the pore-scale domain. This packing method employs trilateration equations to pack spheres with a predefined grain size distribution (GSD of hydrogel beads) and a given porosity (To et al, 2016). In addition, the boundary conditions are specified, as shown in Figure 2.…”

“…The DEM proposed by Cundall and Strack [63] was used to simulate the packing process of particles under the action of gravity. Although there are some new packaging algorithms which are more efficient and flexible [64], DEM is still the closest algorithm to the real gravity packing process. In this study, the DEM was implemented by the software of PFC3D.…”

“…In order to obtain the free and skeleton particles in the soil, the first step is to create a soil model considering the particle distribution. In DEM modelling, there are several techniques to prepare soil samples: (1) random filling method [12,9]; (2) expansion method [3,15]; (3) meshbased method [9,19]; (4) compaction method [20]; (5) constructional method [3,11,40]; (6) gravity settlement method [11,39]. The first three methods have difficulties in generating a particle distribution with a specified gradation.…”
