ClementiDihedral #

It is specific to Off-lattice Go forcefield.

\[U(v) = k_1(1-\cos(v-v_0)) + k_3(1-\cos(3(v-v_0)))\]

It is introduced in the following paper.

C. Clementi, H. Nymeyer, J. Onuchic, (2000) JMB

Example #

[[forcefields.local]]
interaction = "DihedralAngle"
potential   = "ClementiDihedral"
topology    = "none"
parameters  = [
    {indices = [0,1,2,3], v0 = -2.20, k1 = 1.0, k3 = 0.5},
    # ...
]

Input Reference #

v0: Floating
- It determines the minimum of the potenital.
k1: Floating
- It determines the strength of the potential.
k3: Floating
- It determines the strength of the potential.
indices: Array of Integers (length = 4)
- Indices of particles that interact with each other. The index is 0-based.
offset: Integer(Optional. By default, 0.)
- Offset of index.
