lost atom error

​ Hi Dear all

I want to simulate a nano-channel and use the fix boundary condition in the z direction as follows:

boundary p p f

I use the thermo_modify lost ignore after the thermo_style command,

timestep 0.005
thermo 200
thermo_style custom step temp press

dump 1 all xyz 100 Argon.xyz
dump 2 all movie 50 movie.mpg type type zoom 1 size 1280 720 box yes 0.01

thermo_modify lost ignore

run 1000000

but I still encounter “lost atom” error
What is the problem?

Have you tried: thermo_modify lost warn
In this condition, the code should continue only with a warning.
It works for me and maybe you too.

​there is not enough information here to say anything without speculation.​

​please provide the usual information (LAMMPS version, OS/Version/Platform
you are running on) and a minimal and complete(!) input deck that can
reproduce the issue.
