       -## Package features
       +A flexible and computationally efficient 2d implementation of the discrete element method.  Sea-ice floes are represented as particles, which can be forced by ocean and atmospheric velocity fields.  The ice floes interact through elasto-viscous-frictional contact rheologies and obtain time-dependent tensile strength.
