[lammps-users] Numbering of atoms?

Dear Steve,

Quick question: Does the numbering atoms or their global order between to consecutive runs change? For instance:

run 100
run 200

My algorithm depends on the initial positions of atoms, however if their order change between runs, them I get wrong results since I can not point to the right atom anymore. Any suggestion?

Thank you, Javier

Atoms are numbered once at the beginning and then never change.
I don't know what you mean by "global order". If running in
parallel, atoms move between procs, and are written into
the dump file in random order. But atom N will always be atom N.
