This class implements an interaction between pairs of particles that varies harmonically with the distance between them.
To use it, create a AmoebaHarmonicBondForce object then call addBond() once for each bond. After a bond has been added, you can modify its force field parameters by calling setBondParameters().
def __del__ | ( | self | ) |
__del__(self)
Reimplemented from Force.
def __init__ | ( | self, | ||
args | ||||
) |
__init__(self) -> AmoebaHarmonicBondForce __init__(self, AmoebaHarmonicBondForce other) -> AmoebaHarmonicBondForce
Create a Amoeba HarmonicBondForce.
def addBond | ( | self, | ||
args | ||||
) |
addBond(self, int particle1, int particle2, double length, double quadraticK) -> int
Add a bond term to the force field.
particle1 | the index of the first particle connected by the bond | |
particle2 | the index of the second particle connected by the bond | |
length | the equilibrium length of the bond, measured in nm | |
k | the quadratic harmonic force constant for the bond |
def getAmoebaGlobalHarmonicBondCubic | ( | self | ) |
getAmoebaGlobalHarmonicBondCubic(self) -> double
