/* ERROR/WARNING messages:
E: MEAM library error %d
A call to the MEAM Fortran library returned an error.
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: Incorrect args for pair coefficients
Self-explanatory. Check the input script or data file.
E: Pair style MEAM requires newton pair on
See the newton command. This is a restriction to use the MEAM
potential.
E: Cannot open MEAM potential file %s
The specified MEAM potential file cannot be opened. Check that the
path and name are correct.
E: Incorrect format in MEAM potential file
Incorrect number of words per line in the potential file.
E: Unrecognized lattice type in MEAM file 1
The lattice type in an entry of the MEAM library file is not
valid.
E: Did not find all elements in MEAM library file
The requested elements were not found in the MEAM file.
E: Keyword %s in MEAM parameter file not recognized
Self-explanatory.
E: Unrecognized lattice type in MEAM file 2
The lattice type in an entry of the MEAM parameter file is not
valid.
