BondAngleInteraction #

BondAngleInteraction depends on the angle formed by 3 particles.

The following potentials are available.

• Harmonic
• Gaussian
• FlexibleLocalAngle

Example #

[[forcefields.local]]
interaction = "BondAngle"
potential   = "Harmonic"
topology    = "none"
parameters  = [
    # required parameters depend on a potential...
    {indices = [0, 1, 2], offset = 100, ... },
]

Input Reference #
