• This paper presents a numerical scheme for a solid–fluid coupled discrete-element method (DEM) that takes into consideration
  solid deformation and pore pressure generation and dissipation. Analytical solutions of conventional soil mechanics examples obtained by
  oedometer testing are used to quantitatively validate the proposed algorithm. The numerical results show good agreement with the analytical
  solutions. The proposed method advances the current capability of solid–fluid coupled DEM analysis to simulate the mechanical behavior of
  saturated granular materials.
