Introduction to the Discrete Element Method (DEM),nt methods are introduced and defined. The calculation cycle, including equations of motion for grid points and constitutive models for zones and contact, are explained. The differential and discrete forms of the equations of motion are presented. The contact detection is an important part of the di

DEM Coupled with Dynamic Fluid Mesh (DFM), the discrete element method (DEM) to model fluid-solid interactions. The approach considers permeability and porosity changes resulting from soil skeleton deformation and suffusion. The simulation process begins by setting up the DEM model and generating a fluid mesh based on the coarse particles i

DEM Coupled with Lattice-Boltzmann Method (LBM),tional fluid dynamics (CFD) approaches. Instead of solving Navier–Stokes equations, the LBM uses a discrete mesoscopic approach that represents fluid as discrete parcels moving in a fixed lattice, subject to simple collision rules. As a result, an LBM solver is simpler and more computationally effic

Hydraulic Stimulation of Naturally Fractured Reservoirs,he fractures included in the discrete fracture network. The advantage of this approach is relative increase in computational efficiency. The disadvantage is inability to simulate general fracture trajectory in complex stress state. Thus, the described methodology is recommended when fluid injection
