Dear all,
I am trying to simulate my system using namd with the amber-style force field.
Everything was fine! However I found there is a bond between the two Hydrogens of
the TIP3P water in Amber force field. For what reason they put a bond between the
two Hydrogen? Any comments? Thanks in advance!

Best!
Ming
