etomica.models.nitrogen.HarmonicDisorderedAlphaNitrogenModelPairMoleculeSequentialLS

public class HarmonicDisorderedAlphaNitrogenModelPairMoleculeSequentialLS
extends Simulation

Disordered alpha-phase This class is created to take care of Java out of memory problem when creating a 2D array that is gigantic [~10000][~10000] The class is write a 3 x (nA * dof) Matrix to file while looping through the molecules This class also applied the molecules pair identification algorithm to speed up the matrix construction. with lattice sum
