P2HeTI

public P2HeTI(double temperature)

Method Detail

energy

public double energy(IAtomList atoms)

Description copied from interface: IPotentialAtomic

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

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

setBox

public void setBox(Box box)

Description copied from interface: IPotential

Informs the potential of the box on which it acts so that it can properly consider the boundaries.

Specified by:

setBox in interface IPotential

nBody

public int nBody()

Description copied from interface: IPotential

The number of atoms on which the potential depends.

Specified by:

nBody in interface IPotential

u

public double u(double r2)

Description copied from interface: Potential2Spherical

The pair energy u(r^2) with no truncation applied.

Specified by:

u in interface Potential2Spherical

Parameters:

r2 - the square of the distance between the particles.
