"description" "This test computes the potential energy and forces of a periodic orthogonal box of 64 silicon atoms. The atomic positions for this test were obtained by first initializing the atoms in a 2x2x2 unit cell diamond configuration with a lattice constant of 5.431 Angstroms (conventional unit cell). The box dimensions were then held fixed and dynamics were performed in LAMMPS (http://lammps.sandia.gov) under a Tersoff (T2) potential by heating the atoms to ~4100K using a Langevin thermostat for 2000 time steps (each time step was 0.001ps). The system was then cooled to 0K using a Langevin thermostat for 15000 timesteps. Finally, static minimization of the positions (using the conjugate gradient algorithm in LAMMPS) was performed under the T2 potential."
