/* 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: FixEOStableRXKokkos requires a fix rx command.
The fix rx command must come before the pair style command in the input file
E: There are no rx species specified
There must be at least one species specified through the fix rx command
E: Invalid eos/table/rx length
The eos/table/rx table must have more than one entry.
E: eos/table/rx values are not increasing
The equation-of-state must an increasing function
E: FixEOStableRX requires atom_style with internal temperature and energies (e.g. dpd)
Self-explanatory.
E: Internal temperature <= zero.
Self-explanatory.
E: Cannot open eos table/rx potential file %s
Self-explanatory.
E: Incorrect format in eos table/rx file
Self-explanatory.
E: Cannot open file %s
Self-explanatory.
E: Did not find keyword in table file
Self-explanatory.
E: Illegal fix eos/table/rx command
Incorrect number of arguments specified for the fix eos/table/rx command.
E: Invalid keyword in fix eos/table/rx parameters
Self-explanatory.
E: The number of columns in fix eos/table/rx does not match the number of species.
Self-explanatory. Check format for fix eos/table/rx file.
E: fix eos/table/rx parameters did not set N
The number of table entries was not set in the eos/table/rx file
W: Secant solver did not converge because table bounds were exceeded
The secant solver failed to converge, resulting in the lower or upper table bound temperature to be returned
E: NaN detected in secant solver.
Self-explanatory.
E: Maxit exceeded in secant solver
The maximum number of interations was exceeded in the secant solver
