It's being generated internally in the ReaxFF library. You
could grep for it there. I'll ask Aidan if he has any insight.

This is an error generated in the ReaxFF library:
[[email protected]... lammps_svn]$ grep -i 'unknown bond' lib/reax/*.F
lib/reax/reax_connect.F: write (*,*)qa(i1),'-',qa(i2),'Fatal: Unknown
bond in molecule'
lib/reax/reax_connect.F: write (*,*)qa(i1),'-',qa(i2),'Fatal: Unknown
bond in molecule'
It indicates that you have specified a geometry containing a bond between a
pair of atoms for which bond parameters have not been specified. It is
difficult for me to predict why that might be, as I have never managed to do
such a thing.
