Hello Dr Lemkul,

Thank you for the clarification. To summarize: If I have a bond between two
atoms and one of the atoms has a topology "atom" field that begins with the
letter "H," "constraints=h-bonds" will transform it into a constraint.


Exactly.

I have another question. When specifying this "constrained bond," I have an
equilibrium distance but I do not have a force-constant. Is it irrelevant
what value I choose for the force constant if I apply constraints to that
bond?


Yes.
