Detailed Description

This class encapsulates a general timestep solver concept to solve linear PDE in time and space. Any linear partial differential equation of the form

where D_n, ..., D₀ are space operators that not depend on time. After the discretisation it can always be brought in the form

where the LHS depends only on the timestep size and the RHS can be evalated from previous steps. Therefore the new solution Y_n is best obtained with an LU separation of the LHS.

Constructor

Parameters

timeStepStrategy

Timestep strategy for solving the PDE

Member Function Documentation

info()

virtual std::ostream & timestepping::TimeStepping::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

operator()()

void timestepping::TimeStepping::operator()	(	concepts::Vector< Real > &	sol,
		uint	n
	)

Returns the solution of the n'th timestep. With the parameter n the actual solution is return, otherwise the specified step in the futur. A step number n before the actual step number is not possible and throws an exception

Parameters

sol	New solution vector
n	Step number of the solution n
