Model driver that supports parametrizations of the Tersoff-style three-body potential. It is ported from LAMMPS and supports the same format for parameter files. The commonly used variants by Tersoff and Nord/Albe/Erhart/Nordlund are supported, see source citations for details. Optionally, a Ziegler-Biersack-Littmark potential for short interatomic distances can be smoothly joined via a Fermi function. This functionality mirrors the tersoff/zbl variant in LAMMPS.
