[lammps-users] lost atoms

Hi Everyone,

I am using
pair_style buck 2.5
pair_coeff * * 1687061.32 0.135 1500

When I am run a simulation for indentation, it shows a error:

Lost atom: original 422 current 52

Is this error beacuse of wrong choice of potential and its argument or may be because of some other error.
I am also attaching my input file if you want to have a look at it (plaese do suggest if something’s wrong there).

Thnaks in advance.

There's many reasons you could lose atoms, one of which
is if your potential is parameterized incorrectly. Try to
figure out why your atoms are flying out of the simulation
