Class template Dune::GDT::FractionalTimeStepper¶
Inherits from Dune::GDT::TimeStepperInterface.
-
template<class FirstStepperImp, class SecondStepperImp>
class Dune::GDT::FractionalTimeStepper<FirstStepperImp, SecondStepperImp> : public TimeStepperInterface<typename FirstStepperImp::DiscreteFunctionType>¶ Takes two time steppers and performs a simple fractional step scheme (see e.g. LeVeque, “Finite Volume Methods for Hyperbolic Problems”, 2002, Section 17.1). In each time step t, the first stepper is applied up to time t+dt and the result is taken as input for the second time stepper, which is also applied up to time t+dt. Initial values and time are taken from the first time stepper.
