#  IF YOU WANT TO ADD DAMPING, THEN UNCOMMENT THE NEXT LINE:
#fix fxLan  gMobile langevin 0.001 0.001 10000.0 48279
#  To use Langevin dynamics in LAMMPS you need both "fix langevin" and "fix nve"
#  (See http://lammps.sandia.gov/doc/fix_langevin.html for details.)
#  This was not tested.

# For efficient simulation in parallel, try using "fix balance":
# (This will adjust the spatial decomposition as the distribution of
#  particles changes over time.)

# Optional: Improve efficiency by omitting the calcuation of interactions
