TL;DR
This paper introduces a lattice gas model to simulate avalanches in a 2D granular pile, effectively reproducing key features of real sandpile behavior such as outflow statistics and finite-size effects.
Contribution
The paper presents a novel lattice gas model that efficiently simulates avalanche dynamics in granular piles, capturing non-critical behaviors observed in real sandpiles.
Findings

Captures finite-size effects in pile evolution
Demonstrates efficiency of the simulation algorithm
Abstract
A granular media lattice gas (GMLG) model is used to study avalanches in a two-dimensional granular pile. We demonstrate the efficiency of the algorithm by showing that several features of the non-critical behaviour of real sandpile surfaces, such as the bounded outflow statistics or the finite-size effect of the time evolution of the pile mass, can be reproduced by this simulation approach.
