Discrete Element Modelling (DEM) is a technique used widely throughout science and engineering. It offers a convenient method with which to numerically simulate a system prone to developing discontinuities within its structure. Often the technique gets overlooked as designing and implementing a model on a scale large enough to be worthwhile can be both time(More)
Within Computer Science, reusability of specific modular software components is generally accepted as best practice. Simulation techniques such as Discrete Element Modelling (DEM) rely on the well defined problems of Newtonian physics, and while differences exist in the methods defined to compute solutions to these problems, each method follows the same(More)
Clutter within information visualization (infovis) systems is an area of continuing concern and is receiving increasing research interest. Solutions to the problem vary in their approach, ranging from novel visualizations designed specifically to cope with high data density, through to statistical methodologies such as binning. This paper presents a(More)
Discrete Element Modelling (DEM) is a numerical technique that uses a system of interacting discrete bodies to simulate the movement of material being exposed to external forces. This technique is often used to simulate granular systems; however by adding further elements that interconnect the bodies, it can be used to simulate the deformation of a large(More)
