Detailed Description

template<class TDomain, class TAlgebra>
class ug::ITimeIntegrator< TDomain, TAlgebra >

Integrates over a given time interval [a,b] with step size dt.

Member Function Documentation

apply() [1/2]

template<class TDomain, class TAlgebra>

void ug::ITimeIntegrator< TDomain, TAlgebra >::apply ( grid_function_type & u1, const grid_function_type & u0 )

inline

Apply operator.

This method applies the operator, i.e, advances the time step

apply() [2/2]

template<class TDomain, class TAlgebra>

virtual bool ug::ITimeIntegrator< TDomain, TAlgebra >::apply ( SmartPtr< grid_function_type > u1, number t1, ConstSmartPtr< grid_function_type > u0, number t0 )

pure virtual

Implemented in ug::LimexTimeIntegrator< TDomain, TAlgebra >.

init() [1/2]

template<class TDomain, class TAlgebra>

void ug::ITimeIntegrator< TDomain, TAlgebra >::init ( )

inline

init operator

This method initializes the operator. Once initialized the 'apply'-method can be called.

Returns

bool success flag

init() [2/2]

template<class TDomain, class TAlgebra>

virtual void ug::ITimeIntegrator< TDomain, TAlgebra >::init ( grid_function_type const & u )

inlinevirtual

init operator depending on a function u

This method initializes the operator. Once initialized the 'apply'-method can be called. The function u is passed here, since the linear operator may be the linearization of some non-linear operator. Thus, the operator depends on the linearization point. If the operator is not a linearization, this method can be implemented by simply calling init() and forgetting about the linearization point.

Parameters

[in]

u

function (linearization point)

Returns

bool success flag

Reimplemented in ug::TimeIntegratorLinearAdaptive< TDomain, TAlgebra >.
