BondLengthInteraction #

BondLengthInteraction is an interaction that depends on the distance between particles.

The following potentials are available.

• Harmonic
• Gaussian
• GoContact
• AttractiveGoContact
• RepulsiveGoContact
• WormLikeChain
• WormLikeChainOffset
• 3SPN2Bond

Example #

[[forcefields.local]]
interaction = "BondLength"
potential   = "Harmonic"
topology    = "bond"
parameters  = [
    # required parameters depend on a potential...
    {indices = [0, 1], offset = 100, ... },
]
