/* ERROR/WARNING messages:
E: Change_box command before simulation box is defined
Self-explanatory.
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 change_box 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 change_box group ID
Group ID used in the change_box command does not exist.
E: Cannot change_box in z dimension for 2d simulation
Self-explanatory.
E: Change_box volume used incorrectly
The "dim volume" option must be used immediately following one or two
settings for "dim1 ..." (and optionally "dim2 ...") and must be for a
different dimension, i.e. dim != dim1 and dim != dim2.
E: Cannot change_box in xz or yz for 2d simulation
Self-explanatory.
E: Cannot change box tilt factors for orthogonal box
Cannot use tilt factors unless the simulation box is non-orthogonal.
E: Cannot change box z boundary to nonperiodic for a 2d simulation
Self-explanatory.
E: Cannot change box to orthogonal when tilt is non-zero
Self-explanatory.
E: Cannot change box ortho/triclinic with dumps defined
This is because some dumps store the shape of the box. You need to
use undump to discard the dump, change the box, then redefine a new
dump.
E: Cannot change box ortho/triclinic with certain fixes defined
This is because those fixes store the shape of the box. You need to
use unfix to discard the fix, change the box, then redefine a new
fix.
W: Lost atoms via change_box: original %ld current %ld
The command options you have used caused atoms to be lost.
