LAMMPS (18 Feb 2013)
# This script reproduces stress trajectories from Fig. 1 in
# Ravelo, Holian, Germann, and Lomdahl, PRB 70 014103 (2004)
#
# Three thermostatting scenarios are visited: undamped (nodrag),
# damped (drag) and Nose-Hoover chain (nhchains).
#
# The axial and shear stress trajectories are printed to the
# file "stress_vs_t.dat". For the damped case, the original figure
# seems to be a plot of 2*tau, rather than tau.
#
# The script also demonstrates how to
# orient a crystal along <110>,
# and how to use the lj/cubic pair style.
