/* 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: Pair dpd/fdt/energy requires ghost atoms store velocity
Use the communicate vel yes command to enable this.
E: Pair dpd/fdt/energy requires newton pair on
Self-explanatory.
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.
