Towards dense, realistic granular media in 2D

The development of an applicable theory for granular matter - with both qualitative and quantitative value - is a challenging prospect, given the multitude of states, phases and (industrial) situations it has to cover. Given the general balance equations for mass, momen- tum, and energy, the limiting case of dilute and almost elastic granular gases, where kinetic theory works per- fectly well, is the starting point.
