Description

template<class Scalar>
class Dumux::TimeLoopBase< Scalar >

Manages the handling of time dependent problems.

This class facilitates the time management of the simulation. It doesn't manage any user data, but keeps track of what the current time, time step size and "episode" of the simulation is. It triggers the initialization of the problem and is responsible for the time control of a simulation run.

The time manager allows to specify a sequence of "episodes" which determine the boundary conditions of a problem. This approach is handy if the problem is not static, i.e. the boundary conditions change over time.

An episode is a span of simulated time in which the problem behaves in a specific way. It is characterized by the (simulation) time it starts, its length and a consecutive index starting at 0.

Note

Time and time step sizes are in units of seconds

Abstract base class needs virtual constructor.

Member Function Documentation

advanceTimeStep()

template<class Scalar >

virtual void Dumux::TimeLoopBase< Scalar >::advanceTimeStep ( )

pure virtual

Advance to the next time step.

Implemented in Dumux::TimeLoop< Scalar >, and Dumux::CheckPointTimeLoop< Scalar >.

finished()

template<class Scalar >

virtual bool Dumux::TimeLoopBase< Scalar >::finished ( ) const

pure virtual

Returns true if the simulation is finished.

Implemented in Dumux::TimeLoop< Scalar >.

maxTimeStepSize()

template<class Scalar >

virtual Scalar Dumux::TimeLoopBase< Scalar >::maxTimeStepSize ( ) const

pure virtual

Get the maximum possible time step size \(\mathrm{[s]}\).

Implemented in Dumux::TimeLoop< Scalar >, and Dumux::CheckPointTimeLoop< Scalar >.

setTimeStepSize()

template<class Scalar >

virtual void Dumux::TimeLoopBase< Scalar >::setTimeStepSize ( Scalar  dt )

pure virtual

Set the current time step size to a given value.

Parameters

dt	The new value for the time step size \(\mathrm{[s]}\)

Implemented in Dumux::TimeLoop< Scalar >.

time()

template<class Scalar >

virtual Scalar Dumux::TimeLoopBase< Scalar >::time ( ) const

pure virtual

timeStepSize()

template<class Scalar >

virtual Scalar Dumux::TimeLoopBase< Scalar >::timeStepSize ( ) const

pure virtual

Returns the suggested time step length \(\mathrm{[s]}\).

Implemented in Dumux::TimeLoop< Scalar >.
