LocalForceField #

LocalForceField contains a set of interactions that affects specific particles.

BondLengthInteraction #

It depends on the distance between two particles.

BondAngleInteraction #

It depends on the angle formed by 3 particles.

DihedralAngleInteraction #

It depends on the angle formed by 2 planes, where each plane is defined by 3 particles.

ContactInteraction #

It depends on the distance between two particles.

Basically it is the same as BondLength. But it consider the case when two particles are too distant and exceeds the cutoff range.

DummyInteraction #

It does not do anything. It is used to define topology without applying force.

See Topology for detail.

3SPN2BaseStacking #

It is specific to 3SPN2 Coarse-Grained DNA model.
