Coarse-grained discrete element method for granular shear flow
Chemical Engineering Journal Advances, 2020 Powder mixing process plays an important role in chemical industries. In manufacturing sectors, there is a great demand for developing a coarse-grained model of a discrete element method (DEM) to perform DEM simulations of powder mixing processes at the ...

A discrete element method representation of an anisotropic elastic continuum [PDF]
, 2018 A method for modeling cubically anisotropic elasticity within the discrete element method is presented. The discrete element method (DEM) is an approach originally intended for modeling granular materials (sand, soil, and powders); however, recent ...

Discrete-element-method model for frictional fibers
Physical Review E, 2023 We present a Discrete Element Method algorithm for the simulation of elastic fibers in frictional contacts. The fibers are modeled as chains of cylindrical segments connected to each other by springs taking into account elongation, bending and torsion forces.

Fully discrete finite element data assimilation method for the heat equation [PDF]
, 2017 We consider a finite element discretization for the reconstruction of the final state of the heat equation, when the initial data is unknown, but additional data is given in a sub domain in the space time.

Virtual Element Methods for hyperbolic problems on polygonal meshes [PDF]
, 2016 In the present paper we develop the Virtual Element Method for hyperbolic problems on polygonal meshes, considering the linear wave equations as our model problem. After presenting the semi-discrete scheme, we derive the convergence estimates in H^1 semi-
