collisionTime

public double collisionTime(IAtomList pair,
                            double falseTime)

Description copied from class: P2HardSphere

Time to collision of pair, assuming free-flight kinematics

Specified by:

collisionTime in interface PotentialHard

Overrides:

collisionTime in class P2HardSphere

bump

public void bump(IAtomList pair,
                 double falseTime)

Implements collision dynamics and updates lastCollisionVirial

Specified by:

bump in interface PotentialHard

Overrides:

bump in class P2HardSphere

energy

public double energy(IAtomList pair)

Description copied from class: Potential2HardSpherical

Energy of the pair as given by the u(double) method, with application of any PotentialTruncation that may be defined for the potential. This does not take into account any false positioning that the Integrator may be using.

Specified by:

energy in interface IPotentialAtomic

Overrides:

energy in class Potential2HardSpherical
