Basic formulation of the discrete element formulation using spherical or cylindrical particles was first proposed by Cundall and Strack. Similar formulation has been developed in CIMNE and implemented in the explicit dynamic discrete/finite element code DEMPack.

The code DEMPack has a lot of original features like modelling of tool wear in rock cutting, thermomechanical coupling and other capabilities not present in commercial discrete element codes.
