# 3d Lennard-Jones melt
#
# This example requires that the KIM Simulator Model (PM)
# Sim_LAMMPS_ReaxFF_StrachanVanDuinChakraborty_2003_CHNO__SM_107643900657_000
# is installed.  This can be done with the command
#   kim-api-collections-management install user Sim_LAMMPS_ReaxFF_StrachanVanDuinChakraborty_2003_CHNO__SM_107643900657_000
# If this command does not work, you may need to setup your PATH to find the utility.
# If you installed the kim-api using the LAMMPS CMake build, you can do the following
# (where the current working directory is assumed to be the LAMMPS build directory)
#   source ./kim_build-prefix/bin/kim-api-activate
# If you installed the kim-api using the LAMMPS Make build, you can do the following
# (where the current working directory is assumed to be the LAMMPS src directory)
#   source ../lib/kim/installed-kim-api-X.Y.Z/bin/kim-api-activate
# (where you should relplace X.Y.Z with the appropriate kim-api version number).
