Interface PotentialTruncated

All Superinterfaces:

IPotential, IPotentialAtomic

All Known Implementing Classes:

P2SoftSphericalTruncated, P2SoftSphericalTruncatedForceShifted, P2SoftSphericalTruncatedShifted, P2SoftTruncated

public interface PotentialTruncated
extends IPotentialAtomic

Interface for a potential that is artificially truncated, and thus which can provide a zero-body potential that (approximately) corrects for the truncation. The PotentialMaster gets a LRC potential from a potential implementing this interface when the potential is given to the PotentialMaster's setSpecies method. PotentialGroup also recognizes this interface and adds a LRC potential to the PotentialMaster when a PotentialTruncated is added to it via the type-specifying addPotential method.
