Dry granular avalanche flows are a common in both
the natural geophysical environment and industry, and oc-
cur across many orders of magnitude. Common examples
range from: rock slides, containing upwards of 1000m3
material; to the flow of sinter, pellets and coke into a blast
furnace for iron-ore melting; down to the flow of sand in
an hour-glass.
Molecular Dynamics (MD) algorithms are an extremely
powerful tool to investigate the effects of these and other
factors and with the rapid recent improvement in compu-
tational power the full simulation of the flow in a small
