Restraint Potential Functions
Functional forms for restraint potentials
Below are listed the interaction forms available for restraining potentials acting on individual atoms. All functional forms have an implied origin / reference coordinate defined by some other means (e.g. specified when adding additional potentials to configurations) with $r = r_{i} - r_{origin}$.
