What is the neighbor list in LAMMPS?

Hi LAMMPS users,

What is the neighbor list in LAMMPS? Is it used for calculating force? If I do not use the commands ‘neighbor’ or ‘neighbor_modify’, will the neighbor lists still be built?

Bests,

this is a *very* basic question. i strongly suggest to read up
on the details in a text book about MD simulations or at the
very least check out this URL: http://lmgtfy.com/?q=neighbor+list+md

the short answer is: neighbor lists are a method to speed
up computing non-bonded interactions with a cutoff.

do not use the commands 'neighbor' or 'neighbor_modify', will the neighbor
lists still be built?

yes. neighbor lists usually are "requested" by pair styles.
if you don't use the neighbor command, its default settings
will be used, as it is mentioned in the neighbor manual page.
