This is a molecular dynamics program for simulating 2D (Helle-Shaw cells) granular systems. Currently we are studying systems composed by repulsive granular disks. This system is comprised by disks with a permanent magnetic moment, and the system is built in such a manner that these magnetic moments are parallel between each disk.

Chain forces, which have been observed to form in other granular systems, are also observed in these systems. Below, the figure shows the chain forces occurring in the system.
