/* ERROR/WARNING messages:
E: Cannot dump sort on atom IDs with no atom IDs defined
Self-explanatory.
E: Dump sort column is invalid
Self-explanatory.
E: Too many atoms to dump sort
Cannot sort when running with more than 2^31 atoms.
E: Too much per-proc info for dump
Number of local atoms times number of columns must fit in a 32-bit
integer for dump.
E: Cannot open gzipped file
LAMMPS is attempting to open a gzipped version of the specified file
but was unsuccessful. Check that the path and name are correct.
E: Cannot open dump file
The output file for the dump command cannot be opened. Check that the
path and name are correct.
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.
