                                        Vector[] vex)

Method Detail

nearestImage

public void nearestImage(Vector dr)

Description copied from class: Boundary

The nearest image is the pair of atom images that are closest when all periodic-boundary images are considered.

If the vector passed to this method is the displacement vector between two points, the vector will be transformed such that it corresponds to the vector between the nearest image of those two points.

Overrides:

nearestImage in class BoundaryDeformablePeriodic

Parameters:

dr - the vector to be transformed

centralImage

public Vector centralImage(Vector r)

Description copied from class: Boundary

Determines the translation vector needed to apply a periodic-image transformation that moves the given point to an image point within the boundary (if it lies outside, in a direction subject to periodic imaging).

Overrides:

centralImage in class BoundaryDeformablePeriodic

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

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).

Overrides:

getPeriodicity in class BoundaryDeformablePeriodic

Parameters:

d - the dimension of the desired periodicity

Returns:

the periodicity of dimension d

isDoPBC

public boolean isDoPBC()

setDoPBC

public void setDoPBC(boolean doPBC)
