This is the companion code to A Variational Integrator for the Discrete Element Method.
Figures for the various examples in the paper can be generated
by running the scripts in examples.
Comparisons to LAMMPS can be made by running the run.sh
scripts in subdirectories of the lammps folder, provided
that LAMMPS is installed and available through the lmp command.
The figures can be plotted using LaTeX and pgfplots by running
make in the top level directory.
