Detailed Description

An Integrator defines a method for simulating a System by integrating the equations of motion.

This is an abstract class. Subclasses define particular integration methods.

Each Integrator object is bound to a particular Context which it integrates. This connection is specified by passing the Integrator as an argument to the constructor of the Context.

Member Function Documentation

def getConstraintTolerance (   self)

getConstraintTolerance(Integrator self) -> double

Get the distance tolerance within which constraints are maintained, as a fraction of the constrained distance.

References simtk.openmm.openmm.stripUnits().

def getStepSize (   self)

getStepSize(Integrator self) -> double

Get the size of each time step, in picoseconds. If this integrator uses variable time steps, the size of the most recent step is returned.

def setConstraintTolerance (   self,
  args 
)

setConstraintTolerance(Integrator self, double tol)

Set the distance tolerance within which constraints are maintained, as a fraction of the constrained distance.

References simtk.openmm.openmm.stripUnits().

def setStepSize (   self,
  args 
)

setStepSize(Integrator self, double size)

Set the size of each time step, in picoseconds. If this integrator uses variable time steps, the effect of calling this method is undefined, and it may simply be ignored.

Parameters
sizethe step size, measured in ps

References simtk.openmm.openmm.stripUnits().

def step (   self,
  args 
)

step(Integrator self, int steps)

Advance a simulation through time by taking a series of time steps.

Parameters
stepsthe number of time steps to take
