int IA_Neighbor_List::n_neighbors

number of interacting neighbor cells .

A word about the interacting neighbor cells:

In a 3D lattice each cell has 27 neighbors (including itself!). Since we deal with pair forces, it is sufficient to calculate only half of the interactions (Newtons law: actio = reactio). For each cell 13+1=14 neighbors. This has only to be done for the inner cells.

Caution: This implementation needs double sided ghost communication! For single sided ghost communication one would need some ghost-ghost cell interaction as well, which we do not need!

It follows: inner cells: n_neighbors = 14 ghost cells: n_neighbors = 0
