/* 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: Compute ID for fix pafi does not exist
Self-explanatory.
E: Compute for fix pafi does not calculate a local array
Self-explanatory.
E: Compute for fix pafi has < 3*DIM fields per atom
Self-explanatory.
E: Fix pafi requires a damped dynamics minimizer
Use a different minimization style.
