A single sentence description.
Conjugate gradient relaxation of random atomic cluster of Si atoms
Description Computes the potential energy and forces of a random cluster of Si atoms and performs
a conjugate gradient relaxation of the positions. 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.
The supported atomic species.
