This driver is consistent with 'pair_style sw' in the LAMMPS package, but the parameter file has a different format and the driver is less general than the LAMMPS implementation. Specifically, in the KIM parameter file, only independent pairwise parameters are read in and the three-body parameters are generated through geometric averaging. In addition, the costheta_0 parameter is assumed to be the same for all three-body interactions and the tolerance parameter introduced in LAMMPS for efficiency is not supported. See the README file for details. A Python utility "lammps_sw_2_kim_sw.py" is provided to translate LAMMPS 'pair_style sw' parameter files to the KIM model driver format.
