[lammps-users] LAMMPS restart command

Hello,

I have a confusion with LAMMPS restart command “restart N file1 file2”.
N means when I want to output in time.

I am confused with file1 , file2.

Should I use file1 or file2 to start my new simulation?

Also, If I run a simulation for 1000 time steps and in “restart N file1 file2”, I choose N=100 and if my simulation stops at 900 time steps, because the supercomputer does not allow long run simulation, What will be my file1 and file2 in this case?

I used write_restart command, I run simulation for 10^8 time units, but my simulations stopped at 10^7 time units and I was not able to save restart file, to do simulation again from the time it stopped, I did put ‘write_restart’ file after the ‘run’ command.

I read most of the questions in the LAMMPS mailing list but was not able to find a solution to my problem.

Thanks

You use whichever file is newer.

Please review the description of the restart command in the manual and also look at the information given on the read_restart documentation page.
