Detailed Description

This class implements an implicit solvation force using the generalized Kirkwood/Grycuk model.

To use this class, create an AmoebaGeneralizedKirkwoodForce object, then call addParticle() once for each particle in the System to define its parameters. The number of particles for which you define parameters must be equal to the number of particles in the System, or else an exception will be thrown when you try to create a Context. After a particle has been added, you can modify its force field parameters by calling setParticleParameters(). This will have no effect on Contexts that already exist unless you call updateParametersInContext().

Member Function Documentation

def addParticle (   self,
  args 
)

addParticle(AmoebaGeneralizedKirkwoodForce self, double charge, double radius, double scalingFactor) -> int

Add the parameters for a particle. This should be called once for each particle in the System. When it is called for the i'th time, it specifies the parameters for the i'th particle.

Parameters
chargethe charge of the particle, measured in units of the proton charge
radiusthe atomic radius of the particle, measured in nm
scalingFactorthe scaling factor for the particle

def setParticleParameters (   self,

Parameters

def updateParametersInContext (   self,
  args 
)

updateParametersInContext(AmoebaGeneralizedKirkwoodForce self, Context context)

Update the per-particle parameters in a Context to match those stored in this Force object. This method provides an efficient method to update certain parameters in an existing Context without needing to reinitialize it. Simply call setParticleParameters() to modify this object's parameters, then call updateParametersInState() to copy them over to the Context.

The only information this method updates is the values of per-particle parameters. All other aspects of the Force (the probe radius, the surface area factor, etc.) are unaffected and can only be changed by reinitializing the Context.
