/* 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
The output file for the dump command cannot be opened. Check that the
path and name are correct.
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.
