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.

Visualization of Results Received with the Discrete Element Method [PDF]
Computational Methods in Science and Technology, 2009 The output of discrete element simulations includes thousands of time-frames and millions of interacting particles (bodies) in each frame. A single simulation can include terabytes of results, which may lead to very large, very complex data sets. Visualizing them is coupled with difficulties caused by either the number of particles, the number of time ...

The soft discrete element method
Granular Matter, 2021 In order to accelerate simulations of assemblies of highly deformable grains, a novel numerical approach, called Soft Discrete Element Method (SDEM) is presented. It consists in extending the classical DEM by introducing the deformability of the grains in a simplified way.
