/* ERROR/WARNING messages:

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: Invalid dump dcd filename

Filenames used with the dump dcd style cannot be binary or compressed
or cause multiple files to be written.

E: Too many atoms for dump dcd

The system size must fit in a 32-bit integer to use this dump
style.

E: Dump dcd requires sorting by atom ID

Use the dump_modify sort command to enable this.

E: Cannot use variable every setting for dump dcd

The format of DCD dump files requires snapshots be output
at a constant frequency.

E: Cannot change dump_modify every for dump dcd

The frequency of writing dump dcd snapshots cannot be changed.

E: Cannot open dump file

Self-explanatory.

E: Dump dcd of non-matching # of atoms

Every snapshot written by dump dcd must contain the same # of atoms.

E: Too big a timestep for dump dcd

The timestep must fit in a 32-bit integer to use this dump style.
