Cutoff lammps
WebFeb 21, 2024 · According to other questions I checked, LAMMPS uses some unspecified heuristic to extract these bond length estimates, but I cannot understand why they would depend on the neighbor list cutoff. ... The neighbor cutoff is the distance around a particle where the particle’s neighbor list will list out potential pair interaction neighbours.
