[lammps-users] Lammps update neighbours when atoms lost?

Hi, Steve:

I used the command:

thermo_modify lost ignore

Then when atoms move out of my fixed boundary, they’re lost. However, I’m wondering what happens to neighbour list. Do they get updated immediately? If no, there must be a way to label these lost atoms as “non-existent” to avoid problems. If yes, it seems not an efficient way.

Could you help me to clarify this?


The code only detects the atoms are lost on steps when
the neighbor list is re-built, so it does it consistently.
