Direct Known Subclasses:

DataSourceTensorVirialHardProfile

public class DataSourceTensorVirialHard
extends java.lang.Object
implements IDataSource, IntegratorHard.CollisionListener, java.io.Serializable

A MeterTensor that returns the virial component of the pressure tensor for a hard potential. This is the counterpart to MeterVelocityTensor, also called by the surface tension meter.

Method Detail

getDataInfo

public IDataInfo getDataInfo()

Specified by:

getDataInfo in interface IDataSource

getTag

public DataTag getTag()

Specified by:

getTag in interface IDataSource

Returns:

a tag that uniquely identifies the IDataInfo

getData

public IData getData()

Current value of the meter, obtained by dividing sum of collision virial contributions by time elapsed since last call. If elapsed-time interval is zero, returns the value reported at the last call to the method.

Specified by:

getData in interface IDataSource

Returns:

the data given by this source

collisionAction

public void collisionAction(IntegratorHard.Agent agent)

Sums contribution to virial for each collision.

Specified by:

collisionAction in interface IntegratorHard.CollisionListener

collisionValue

public Tensor collisionValue(IntegratorHard.Agent agent)

Contribution to the virial from the most recent collision of the given pair/potential.

setIntegrator

public void setIntegrator(IntegratorHard newIntegrator)

Informs meter of the integrator for its box, and zeros elapsed-time counter

getIntegrator

public IntegratorHard getIntegrator()
