This is a driver, tuned for efficiency, for the Lennard-Jones (LJ) 6-12 pair potential model. It supports the option to be truncated to have zero energy above a specified cutoff radius or shifted to have a continuous energy at the cutoff radius. The driver is capable of supporting multiple species interactions. If only "like-like" interactions are specified then the driver use the Lorentz-Berthelot mixing rules to generate the unlike interaction parameters. See the README file for details. Version 002 fixes the unit conversion for the cutoffs and sigma values.
