Detailed Description

This is a VirtualSite that computes the particle location as a weighted average of two other particle's locations.

Assuming the weights add up to 1, this means the virtual site is on the line passing through the two particles.

Constructor & Destructor Documentation

def __init__	(		self,
			args
	)

init(OpenMM::TwoParticleAverageSite self, int particle1, int particle2, double weight1, double weight2) -> TwoParticleAverageSite init(OpenMM::TwoParticleAverageSite self, TwoParticleAverageSite other) -> TwoParticleAverageSite

Create a new TwoParticleAverageSite virtual site. Normally weight1 and weight2 should add up to 1, although this is not strictly required.

Parameters

particle1	the index of the first particle
particle2	the index of the second particle
weight1	the weight factor (between 0 and 1) for the first particle
weight2	the weight factor (between 0 and 1) for the second particle
