26This directory (ex_model_driver_P_LJ) contains a shifted Lennard-Jones
27pair potential Model driver written in Fortran 90.
28
29 phi(r) = 4 * epsilon * ( (sigma/r)^12 - (sigma/r)^6 ) + shift
30
31where shift is computed so that phi(rcut) = 0.0

33To create a KIM Model from this Model Driver, one parameter file is required.
34This file must have the following format:
35 Line 1: `SpeciesName' string with element symbol
36 Line 1: `cutoff' value in angstroms
37 Line 2: Lennard-Jones `epsilon' value in eV
38 Line 3: Lennard-Jones `sigma' value in Angstroms
