DISCRETE ELEMENT METHOD FOR MULTISCALE MODELING
Journal of Multiscale Modelling, 2010A discrete element method (DEM) has been developed to provide highly accurate and detailed predictions of the Lagrangian particle phase. Especially in this study, DEM has been used together with an Eulerian approach for the fluid phase to look at interphase exchange phenomena in a multiphase-multiscale modeling approach.

DISCRETE FINITE ELEMENT METHOD
Engineering Computations, 1992A numerical technique is described for the analysis of multiple interacting deformable bodies undergoing large displacements and rotations. Each body is considered an individual discrete unit, which is idealized by a finite element model. Discrete finite element models interact with their surroundings through contact stresses, which are continually ...

Engineering Computations, 2004
Discrete element method (DEM) has been extensively used in the laboratory of particulate and multiphase processing at the University of New South Wales (UNSW) to study the fundamentals of particulate matter at a particle scale. This paper briefly reviews the work in the laboratory, which covers the development of simulation techniques and their ...

Finite element method–discrete element method bridging coupling for the modeling of gouge
International Journal for Numerical Methods in Engineering, 2022AbstractWe discuss the multiscale modeling of a granular material trapped between continuum elastic domains. The amorphous granular region, usually termed “gouge,” is under high confinement pressure, to represent the loading of faults at depth. We model the granularity of gouge using the discrete element method (DEM), while the elastic regions ...

An algebraic multigrid method for finite element discretizations with edge elements
Numerical Linear Algebra with Applications, 2002AbstractThis paper presents an algebraic multigrid method for the efficient solution of the linear system arising from a finite element discretization of variational problems in H0(curl,Ω). The finite element spaces are generated by Nédélec's edge elements.A coarsening technique is presented, which allows the construction of suitable coarse finite ...

Experimental Methods in Chemical Engineering: Discrete Element Method—DEM
The Canadian Journal of Chemical Engineering, 2019The discrete element method (DEM) is a time‐driven simulation technique based on a Lagrangian description of particle motion that predicts the flow of granular matter and fine powders in conveying, mixing, drying, and heterogeneous gas‐(liquid)‐solids reactors.

Evaluation of an FPGA Implementation of the Discrete Element Method
2001The Distinct Element Method (DEM) is a numerical method for the simulation of the behaviour of media consisting of discrete particles, and is widely used for process optimisation in the food and pharmaceutical industries. The DEM is very computationally expensive, but has properties that make it amenable to acceleration by reconfigurable computing ...
