Query: A lattice gas model of avalanches in a granular pile   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.
