/* ERROR/WARNING messages:
E: Pair distance < table inner cutoff
Two atoms are closer together than the pairwise table allows.
E: Pair distance > table outer cutoff
Two atoms are further apart than the pairwise table allows.
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 pair_style command
Style of table is invalid for use with pair_style table command.
E: PairTableRX 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: Site1 name not recognized in pair coefficients
The site1 keyword does not match the species keywords specified throug the fix rx command
E: Illegal number of pair table entries
There must be at least 2 table entries.
E: Invalid pair table length
Length of read-in pair table is invalid
E: Invalid pair table cutoff
Cutoffs in pair_coeff command are not valid with read-in pair table.
E: Bitmapped table in file does not match requested table
Setting for bitmapped table in pair_coeff command must match table
in file exactly.
E: All pair coeffs are not set
All pair coefficients must be set in the data file or by the
pair_coeff command before running a simulation.
E: Cannot open file %s
The specified file cannot be opened. Check that the path and name are
correct. If the file is a compressed file, also check that the gzip
executable can be found and run.
E: Did not find keyword in table file
Keyword used in pair_coeff command was not found in table file.
E: Bitmapped table is incorrect length in table file
Number of table entries is not a correct power of 2.
E: Invalid keyword in pair table parameters
Keyword used in list of table parameters is not recognized.
E: Pair table parameters did not set N
List of pair table parameters must include N setting.
E: Pair table cutoffs must all be equal to use with KSpace
When using pair style table with a long-range KSpace solver, the
cutoffs for all atom type pairs must all be the same, since the
long-range solver starts at that cutoff.
E: The number of molecules in CG particle is less than 1e-8
Self-explanatory. Check the species concentrations have been properly set
and check the reaction kinetic solver parameters in fix rx to more for
sufficient accuracy.
