/* ERROR/WARNING messages:

E: Displace_atoms command before simulation box is defined

The displace_atoms command cannot be used before a read_data,
read_restart, or create_box command.

E: Illegal ... command

Self-explanatory.  Check the input script syntax and compare to the
documentation for the command.  You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.

E: Cannot displace_atoms after reading restart file with per-atom info

This is because the restart file info cannot be migrated with the
atoms.  You can get around this by performing a 0-timestep run which
will assign the restart file info to actual atoms.

E: Could not find displace_atoms group ID

Group ID used in the displace_atoms command does not exist.

E: Invalid displace_atoms rotate axis for 2d

Axis must be in z direction.

E: Zero length rotation vector with displace_atoms

Self-explanatory.

W: Lost atoms via displace_atoms: original %ld current %ld

The command options you have used caused atoms to be lost.

U: Use of displace_atoms with undefined lattice

Must use lattice command with displace_atoms command if units option
is set to lattice.
