etomica.space.Boundary

Direct Known Subclasses:

BoundaryPistonCylinder

public class BoundaryRectangularNonperiodic
extends BoundaryRectangular

Boundary that is not periodic in any direction. Volume is specified, but nothing about boundary enforces the dimensions on the atoms. This effect must be introduced with a potential or other construct that is made consistent with the boundary.

BoundaryRectangularNonperiodic

public BoundaryRectangularNonperiodic(Space space)

Make a boundary with unit volume.

Method Detail

centralImage

public Vector centralImage(Vector r)

Returns a vector with all elements zero.

Specified by:

centralImage in class Boundary

Parameters:

r - vector position of untransformed point; r is not changed by this method

Returns:

the displacement that must be applied to r to move it to its central-image location

nearestImage

public void nearestImage(Vector dr)

Does nothing.

Specified by:

nearestImage in class Boundary

Parameters:

dr - the vector to be transformed

imageOrigins

public double[][] imageOrigins(int nShells)

Returns a zero-length vector.

Overrides:

imageOrigins in class BoundaryRectangular

Parameters:

nShells - the number of shells of images to be computed

getIndexIterator

public IndexIteratorSizable getIndexIterator()

Specified by:

getIndexIterator in class Boundary

getPeriodicity

public boolean getPeriodicity(int d)

Description copied from class: Boundary

Returns true if the boundary is periodic in the given direction (as defined by the getEdgeVector method).

Specified by:

getPeriodicity in class Boundary

Parameters:

d - the dimension of the desired periodicity

Returns:

the periodicity of dimension d
