The positions of the atoms in this Test were obtained by first randomly initializing a set of Si atoms in a cubic box of side length 6.2 Angstroms (fixed, reflective boundary conditions). Dynamics were then performed in LAMMPS (http://lammps.sandia.gov) under a Tersoff (T2) potential by heating the system to ~4100K under a Langevin thermostat for 190 timesteps (each timestep = 0.001ps). Finally, the atomic positions were extracted and are used as the initial positions for the relaxation."
