Member Function Documentation

computeTimeStepSize()

virtual double Opm::TimeStepControlInterface::computeTimeStepSize ( const double dt, const int iterations, const RelativeChangeInterface & relativeChange, const AdaptiveSimulatorTimer & substepTimer ) const

pure 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)
relativeChange	Relative change handler
substepTimer	Sub step timer

Returns

suggested time step size for the next step

Implemented in Opm::General3rdOrderController, Opm::HardcodedTimeStepControl, Opm::PIDAndIterationCountTimeStepControl, Opm::PIDTimeStepControl, and Opm::SimpleIterationCountTimeStepControl.

timeStepAccepted()

virtual bool Opm::TimeStepControlInterface::timeStepAccepted ( const double error, const double timeStepJustCompleted ) const

pure virtual

For the general 3rd order controller, the internal shifting of errors and time steps happens here, and hence this method needs to be called for (after) each time step.

Implemented in Opm::General3rdOrderController, Opm::HardcodedTimeStepControl, Opm::PIDAndIterationCountTimeStepControl, Opm::PIDTimeStepControl, and Opm::SimpleIterationCountTimeStepControl.
