I use write_restart command to obtain a restart file, then I use read_restart command to read it. Everything goes well, but when I use velocity command with default “units lattice” option, then I got the message:
ERROR: Use of velocity with undefined lattice.
When I used “units box” option in velocity command, the error message was gone.
Does this mean write_restart did not write lattice info in the restart file? Is it a bug?
