The so-called coarse-grained discrete element method (DEM) is used here for efficient
simulations of large-scale particle systems as its effectiveness has been successfully verified …

The experimental approach has become a major tool increasingly used by volcanologists in
recent decades to investigate the physics of eruptive processes in complement to field and …

Abstract Campbell et al.(1995) modeled long runout landslides as granular flow using a soft
particle code. Their model essentially simulates landslides from first principles, and although …

Pyroclastic density currents are highly dangerous ground-hugging currents from volcanoes
that cause> 50% of volcanic fatalities globally. These hot mixtures of volcanic particles and …

We report numerical simulations on granular shear flows confined between two flat but
frictional sidewalls. Novel regimes differing by their strain localization features are observed …

The. Moreover, we show that the ill-posed domain defined by Barker et al.(J. Fluid Mech.,
vol. 779, 2015, pp. 794–818) transforms into a domain where the flow is unstable but …

Dry, wet, dense, and dilute granular flows have been previously considered fundamentally
different and thus described by distinct, and in many cases incompatible, rheologies. We …

This paper addresses a non-traditional approach for the scaling-law fluid-flows described by
fractal scaling-law vector calculus associated with the Mandelbrot scaling law. Their …

Granular flows are found across multiple geophysical environments and include pyroclastic
density currents, debris flows, and avalanches, among others. The key to describing …

This article presents a new force model for performing quantitative simulations of dense
granular materials. Interactions between multiple contacts (MC) on the same grain are …
