openff.interchange.components.foyer.FoyerElectrostaticsHandler

pydantic model openff.interchange.components.foyer.FoyerElectrostaticsHandler[source]

Bases: PotentialHandler

Handler storing electrostatics potentials as produced by a Foyer force field.

Fields
field type: str = 'Electrostatics'
field periodic_potential: str = 'Ewald3D-ConductingBoundary'
field expression: str = 'coul'
field charges: Dict[TopologyKey, float] = {}
field scale_13: float = 0.0
field scale_14: float = 0.5
field scale_15: float = 1.0
field cutoff: FloatQuantity = <Quantity(9.0, 'angstrom')>
property charges_with_virtual_sites

Get the total partial charge on each atom, including virtual sites.

store_charges(atom_slots: Dict[TopologyKey, PotentialKey], force_field: Forcefield)[source]

Look up fixed charges (a.k.a. library charges) from the force field and store them in self.charges.
