/* 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: Incorrect args for pair coefficients
Self-explanatory. Check the input script or data file.
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: Pair style peri requires atom style peri
Self-explanatory.
E: Pair peri requires an atom map, see atom_modify
Even for atomic systems, an atom map is required to find Peridynamic
bonds. Use the atom_modify command to define one.
E: Pair peri requires a lattice be defined
Use the lattice command for this purpose.
E: Pair peri lattice is not identical in x, y, and z
The lattice defined by the lattice command must be cubic.
E: Fix peri neigh does not exist
Somehow a fix that the pair style defines has been deleted.
E: Divide by 0 in influence function
This should not normally occur. It is likely a problem with your
model.
