/* 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: Fix balance string is invalid
The string can only contain the characters "x", "y", or "z".
E: Fix balance string is invalid for 2d simulation
The string cannot contain the letter "z".
E: Cannot open fix balance output file
Self-explanatory.
