virtual

return the integer corresponding to the given site, along with the indices of the six nearest neighbors

returns, in the vector "neighbors" a list of lattice neighbors of the target site.

◆ displaceBoundaryObject()

void cubicLattice::displaceBoundaryObject	(	int	objectIndex,
		int	motionDirection,
		int	magnitude
	)

virtual

Displace a boundary object (and surface sites) by one of the six primitive cubic lattice directions.

This function moves an object, shifting the type of lattice sites over on the lattice. Surface sites are also moved. Sites that change from being part of the boundary to a surface site adopt the average state of the neighboring sites that weren't formerly part of the boundary object. This function makes use of the fact that primitive translations will not change the total number of boundary or surface sites associated with each object

Parameters

objectIndex	The position in the vector of boundarySites and surfaceSites that the desired object to move is in
motionDirection	Which way to move the object. Follows same convention as lattice neighbors for stencilType=0
magnitude	number of lattice sites to move in the given direction

Reimplemented from simpleModel.
