# --- Running LAMMPS ---
# -------- REQUIREMENTS: ---------
# 1) This example requires building LAMMPS with the "USER-MISC" package.
# (because it makes use of "gaff.lt" which uses dihedral_style fourier)
# To do this, type "make yes-user-misc" before compiling LAMMPS.
# http://lammps.sandia.gov/doc/Section_start.html#start_3
# -------- PREREQUISITES: --------
# The 2 files "run.in.npt", and "run.in.nvt" are LAMMPS
# input scripts which link to the input scripts and data files
# you hopefully have created earlier with moltemplate.sh:
# system.in.init, system.in.settings, system.data
# If not, carry out the instructions in "README_setup.sh".
#
# -- Instructions: --
# If "lmp_mpi" is the name of the command you use to invoke lammps,
# then you would run lammps on these files this way:
lmp_mpi -i run.in.npt # minimization and simulation at constant pressure
lmp_mpi -i run.in.nvt # minimization and simulation at constant volume
#(Note: The constant volume simulation lacks pressure equilibration. These are
# completely separate simulations. The results of the constant pressure
# simulation might be ignored when beginning the simulation at constant
# volume. (This is because restart files in LAMMPS don't always work,
# and I was spending a lot of time trying to convince people it was a
# LAMMPS bug, instead of a moltemplate bug, so I disabled restart files.)
# Read the "run.in.nvt" file to find out how to use the "read_restart"
# command to load the results of the pressure-equilibration simulation,
# before beginning a constant-volume run.
# If you have compiled the MPI version of lammps, you can run lammps in parallel
#mpirun -np 4 lmp_mpi -i run.in.npt
#mpirun -np 4 lmp_mpi -i run.in.nvt
# (assuming you have 4 processors available)
