that is an irrelevant and incorrect distinction, since you were
comparing it to your MC code where you use a *different* method and
then concluded that "in MD" bonds are not fully rigid and "in MC" they
are. this an incorrect generalization and the basis of my criticism.
you are comparing apples and oranges and drawing a wrong conclusion.
the difference you were referring to is the difference between a rigid
body propagator and using a constraint solver and that has little to
do with MD vs. MC.
why not simply admit that you made a mistake?
