Detailed Description

template<unsigned int dim, typename Cell, int NNc_size>
class CellNNIterator< dim, Cell, NNc_size >

Iterator for the neighborhood of the cell structures.

In general you never create it directly but you get it from the CellList structures

It iterate across all the element of the selected cell and the near cells

Note

to calculate quantities that involve a total reduction (like energies) use the CellIteratorSymRed

Template Parameters

dim	dimensionality of the space where the cell live
Cell	cell type on which the iterator is working
NNc_size	neighborhood size
