The DL_MULTI Force Field

The DL_MULTI force field includes the following features:

1. All common forms of non-bonded atom-atom potential;
2. Atom-atom (site-site) Coulombic potentials;
3. Atom-atom (site-site) distributed multipole potentials;

The following DL_POLY_2 force field features should not be used in DL_MULTI :

1. Valence angle potentials;
2. Dihedral angle potentials;
3. Inversion potentials;
4. Improper dihedral angle potentials;
5. 3-body valence angle and hydrogen bond potentials;
6. 4-body inversion potentials;
7. Sutton-Chen density dependent potentials (for metals)
