I have a question on the optimum bin size used for searching neighbors. As far as I understand the code, the optimum bin size is chosen to be a half of the cutoff (for short-range interactions). And the stencil of each bin contains 14 bins for half_bin_newton() algorithm. Is that correct?
If yes, that means there may be some beads that lying inside the cutoff of a atom are missed while building the neighbor list. Does it make the result inaccurate?
Any explanation will be appreciated.
