[lammps-users] Problem in Periodic Boundary Condition

[malay_rana]

Dear All:

I am tryning to simulate a system consisting of Si atoms and C60 molecules using tersoff potential. When I am using “boundary p p p” then the simulation goes fine. But as soon as I apply “boundary p p f” the simulation stops showing error "Lost atoms: original **** current **** ". The box length along Z direction is sufficiently large so that no atom is out of the box. Any suggestion is highly helpful.

Thankx,

malay

How do you know you're not losing an atom(s) in the
non-periodic direction? Have you dumped the coords?
Have you done a visualization of the system near the time
an atom is lost?
