etomica.models.nitrogen.MinimizeBetaNitrogenLatticeParameter

public class MinimizeBetaNitrogenLatticeParameter
extends Simulation

This class is written to minimize the lattice energy of the beta-phase Nitrogen, which has HCP packing with 2 basis atoms using line minimization The varying parameters are: unit cell A: molecule 1 (u[0] through u[4]) and molecule 2 (u[5] through u[9]) unit cell B: molecule 1 (u[0] through u[4]) and molecule 2 (u[5] through u[9]) - 3 translational + 2 rotational There are total of 20 degrees of freedom.
