etomica.lattice.crystal.PrimitiveOrthorhombicHexagonal

public class PrimitiveOrthorhombicHexagonal
extends Primitive

Primitive group for an orthorhombic system. Primitive vectors orthogonal but with a length ratio to acommodate a hexagonal basis. b = (2/sqrt(3))a ; alpha = 90deg.

Method Detail

makeReciprocal

public Primitive makeReciprocal()

Description copied from class: Primitive

Method defining and constructing reciprocal primitive;

Specified by:

makeReciprocal in class Primitive

setSizeA

public void setSizeA(double newA)

Sets A to the given value and B to 2.0/sqrt(3.0)*A

getSizeA

public double getSizeA()

copy

public Primitive copy()

Returns a new, identical instance of this primitive.

Specified by:

copy in class Primitive

update

protected void update()

Specified by:

update in class Primitive

scaleSize

public void scaleSize(double scale)

Description copied from class: Primitive

Scales (multiplies) the size of each primitive vector by the given value.

Specified by:

scaleSize in class Primitive

latticeIndex

public int[] latticeIndex(Vector q)

Description copied from class: Primitive

Returns the index which would give the unit cell containing the given point if the index were passed to a the site method of a sufficiently large lattice that uses this primitive.

Specified by:

latticeIndex in class Primitive

latticeIndex

public int[] latticeIndex(Vector q,
                          int[] dimensions)

Description copied from class: Primitive

Same as latticeIndex(Space.Vector), but gives index for periodic system with number of unit cells in each direction as given by the dimensions array. If lattice index corresponds to a cell outside the range of dimensions, index of image in central cells is returned.

Specified by:

latticeIndex in class Primitive

wignerSeitzCell

public Polytope wignerSeitzCell()

Description copied from class: Primitive

Returns the Wigner-Seitz cell specified by this primitive. The returned cell does not remain tied to the primitive, and will not be updated with changes to the primitive.

Specified by:

wignerSeitzCell in class Primitive

unitCell

public Polytope unitCell()

Returns a new Cuboid with edges of length given by the current values of the primitive vectors.

Overrides:

unitCell in class Primitive

toString

public java.lang.String toString()
