Method Detail

energy

public double energy(IAtomList pair)

Description copied from class: Potential

Returns the interaction energy between the given atoms. There might be 0, 1, 2 or more atoms in the AtomSet.

Specified by:

energy in interface IPotentialAtomic

Specified by:

energy in class Potential

force

public Vector force(IAtomList pair)

getCoreDiameter

public double getCoreDiameter()

setCoreDiameter

public final void setCoreDiameter(double c)

getCoreDiameterDimension

public final Dimension getCoreDiameterDimension()

getRange

public double getRange()

Description copied from interface: IPotential

Returns the range over which the potential applies. IAtoms with a greater separation do not interact.

Specified by:

getRange in interface IPotential

Specified by:

getRange in class Potential

getLambda

public double getLambda()

setLambda

public final void setLambda(double lam)

getLambdaDimension

public final Dimension getLambdaDimension()

getEpsilon

public double getEpsilon()

setEpsilon

public final void setEpsilon(double eps)

getEpsilonDimension

public final Dimension getEpsilonDimension()

setBox

public void setBox(Box box)

Description copied from class: Potential

Informs the potential of the box on which it acts. Typically this requires at least that it update the nearestImageTransformer of its coordinatePair (if it uses one), e.g.: cPair.setNearestImageTransformer(box.boundary());

Specified by:

setBox in interface IPotential

Specified by:

setBox in class Potential
