/* 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 xtc filename
Filenames used with the dump xtc style cannot be binary or compressed
or cause multiple files to be written.
E: Too many atoms for dump xtc
The system size must fit in a 32-bit integer to use this dump
style.
W: No automatic unit conversion to XTC file format conventions possible for units lj
This means no scaling will be performed.
E: Dump xtc requires sorting by atom ID
Use the dump_modify sort command to enable this.
E: Cannot set dump_modify flush for dump xtc
Self-explanatory.
E: Cannot use variable every setting for dump xtc
The format of this file requires snapshots at regular intervals.
E: Cannot change dump_modify every for dump xtc
The frequency of writing dump xtc snapshots cannot be changed.
E: Cannot open dump file
Self-explanatory.
E: Too big a timestep for dump xtc
The timestep must fit in a 32-bit integer to use this dump style.
E: Illegal dump_modify sfactor value (must be > 0.0)
Self-explanatory.
E: Illegal dump_modify tfactor value (must be > 0.0)
Self-explanatory.
