Dear LAMMPS users,
I have a question about bad bond.
Sometimes, because of large vander walls pairwise potential, the LAMMPS showed a waning "too long bond", or even aborted running with error "bad bond".
However, sometimes lammps still run computation even if there is a too long bond. For example, in my simulation, average bond length is 1.1. Here is questioned data
ITEM: BOX BOUNDS
-5.02295 5.02295
-5.8 5.8
-10 10
ITEM: ATOMS
id type mol x y z ix iy iz vx
811 1 25 -2.23361 3.36142 3.22614 45 -2 0 1.0029
812 1 25 -1.39866 3.43565 2.49885 45 -1 0 1.61169
The bond length between atom(id=811) to id(812) is
811 812 11.7266
Absolutely, this is too long bond. But lammps continued runs to the end.
Could some one give the reason? And how to monitor this happenings and how to avoid it ?
Best wishes,
