inline

Construct a cell list starting from the stored particles.

It differ from the get getCellList for an additional parameter, in case the domain + ghost is not big enough to contain additional padding particles, a Cell list with bigger space can be created (padding particles in general are particles added by the user out of the domains)

Template Parameters

CellL CellList type to construct

Parameters

r_cut	interation radius, or size of each cell
enlarge	In case of padding particles the cell list must be enlarged, like a ghost this parameter say how much must be enlarged
no_se3	avoid se_class3 cheking default false

Returns: the CellList

inline

Construct a cell list starting from the stored particles and reorder a vector according to the Hilberts curve.

It differs from the reorder(m) for an additional parameter, in case the domain + ghost is not big enough to contain additional padding particles, a Cell list with bigger space can be created (padding particles in general are particles added by the user out of the domains)

Parameters

m	order of a curve
enlarge	In case of padding particles the cell list must be enlarged, like a ghost this parameter say how much must be enlarged
