US Patent 7797144 Molecular modeling method and system

A molecular modeling method and system to provide a dielectric function that reflects the plurality of models simultaneously used in molecular modeling. For interactions similar to those used during the development of a charge model, the dielectric is similar to the charge model dielectric. In a second embodiment, an approximation for electrostatic/electrodynamics modeling is provided that analyzes charge distribution and determines groups of charges that can be treated as a whole at moderate distances.
