I would like to add a harmonic restraint for an angle between a specific

bond vector and a target vector in 3D space, defined by 3 coordinates. The

resulting force should be updated at every step of the simulation. I'm

having trouble figuring out the best way to go about this from the

documentation and user-defined forces examples, and I'd appreciate any

suggestions.

Thanks!
