Detailed Description

PID controller based adaptive time step control as above that also takes an target iteration into account.

Constructor & Destructor Documentation

Opm::PIDAndIterationCountTimeStepControl::PIDAndIterationCountTimeStepControl	(	const int	target_iterations = 20,
		const double	tol = 1e-3,
		const boost::any &	= boost::any(),
		const bool	verbose = false
	)

constructor

Parameters

target_iterations	number of desired iterations per time step
tol	tolerance for the relative changes of the numerical solution to be accepted in one time step (default is 1e-3) pinfo The information about the parallel information. Needed to compute parallel scalarproducts.
verbose	if true get some output (default = false)

Member Function Documentation

double Opm::PIDAndIterationCountTimeStepControl::computeTimeStepSize ( const double  dt, const int  iterations, const SimulatorState &  state  ) const

virtual

compute new time step size suggestions based on the PID controller

Parameters

dt	time step size used in the current step
iterations	number of iterations used (linear/nonlinear)
state	new solution state

Returns

suggested time step size for the next step

Reimplemented from Opm::PIDTimeStepControl.
