Detailed Description

Abstract strategy class for the class Timestepping.

The task of a derivated strategy class is to implement the specific calculation of the right and left hand side of the equation

$( D + const.(\Delta t) D') Y_n = V(Y_{n-1}, Y_{n-2}, ...),$

The initial conditions are given at time 0.

Member Function Documentation

◆ info()

virtual std::ostream& concepts::OutputOperator::info ( std::ostream & os ) const

protectedvirtualinherited

Returns information in an output stream.

◆ next()

virtual void timestepping::TimeStepStrategy::next ( )

protectedpure virtual

The overloaded member function next() has to calculate the new right hand side and to release the solution vector.

Then the Timestepping solver can set the new solution.

Implemented in timestepping::LimitingTvdRK2, timestepping::TvdRK2, timestepping::Theta, timestepping::RungeKutta4, timestepping::RungeKutta2, timestepping::Nystroem, timestepping::Newmark, timestepping::LimitingEuler, timestepping::Euler, and timestepping::Alpha.

◆ liCo_

concepts::Operator<Real>* timestepping::TimeStepStrategy::liCo_
