[lammps-users] Is it possible to modify the size of the simulation box from reading a restart file?

Hi, everyone,
I equilibrate a system which is constructed from a data file. When I want to do something to this system, I found that the box size is small. Thus, I want to know if it is possible to just extend the box size and none atom will added into it. I know I can just modify the data file a little, but it will take so much time to re-equilibrate the new system. Thanks for any suggestion!

Check the displace_box command with option remap none
