fix nvt

Dear LAMMPS user,
i have a question regarding fix nvt command:
in my input file i have given this command but still while running it is saying that ‘atoms are lost’ i.e., number of atoms are changing.

I have been looking though the manual page for fix nvt but did not find anything helpful regarding this.
Could anybody answer my question or just direct me to the correct documentation page?

Hi

most likely your initial state is unphysical (atoms too close for example). This would lead to huge forces and subsequently lost atoms. You could try to relax your system using nve/limit first.

Cheers

well, that's pretty daunting. You could just look
in doc/Section_errors.html which lists all error messages.

The one about lost atoms has some helpful suggestions.
