VirtualSite

class VirtualSite

A VirtualSite describes the rules for computing a particle’s position based on other particles. This is an abstract class. Subclasses define particular rules. To define a virtual site, create an instance of a VirtualSite subclass and then call setVirtualSite() on the System.

Subclassed by OpenMM::LocalCoordinatesSite, OpenMM::OutOfPlaneSite, OpenMM::SymmetrySite, OpenMM::ThreeParticleAverageSite, OpenMM::TwoParticleAverageSite
