/* 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: Unknown table style in fix eos/table
Style of table is invalid for use with fix eos/table command.
E: Illegal number of eos/table entries
There must be at least 2 table entries.
E: Invalid eos/table length
Length of read-in fix eos/table is invalid
E: eos/table values are not increasing
The EOS must be a monotonically, increasing function
E: FixEOStable requires atom_style with internal temperature and energies (e.g. dpd)
Self-explanatory.
E: Internal temperature < zero
Self-explanatory. EOS may not be valid under current simulation conditions.
E: Cannot open file %s
The specified file cannot be opened. Check that the path and name are
correct.
E: Did not find keyword in table file
Keyword used in fix eos/table command was not found in table file.
E: Invalid keyword in fix eos/table parameters
Keyword used in list of table parameters is not recognized.
E: fix eos/table parameters did not set N
List of fix eos/table parameters must include N setting.
E: Temperature is not within table cutoffs
The internal temperature does not lie with the minimum
and maximum temperature cutoffs of the table
E: Energy is not within table cutoffs
The internal energy does not lie with the minimum
and maximum energy cutoffs of the table
