Detailed Description

template<class X>
class Ewoms::LoopSolver< X >

Preconditioned loop solver.

Implements a preconditioned loop. Using this class every Preconditioner can be turned into a solver. The solver will apply one preconditioner step in each iteration loop.

template<class X >

template<class L , class P >

Ewoms::LoopSolver< X >::LoopSolver	(	L &	op,
		P &	prec,
		real_type	reduction,
		int	maxit,
		int	verbose
	)

inline

Set up Loop solver.

Parameters

op	The operator we solve.
prec	The preconditioner to apply in each iteration of the loop. Has to inherit from Preconditioner.
reduction	The relative defect reduction to achieve when applying the operator.
maxit	The maximum number of iteration steps allowed when applying the operator.
verbose	The verbosity level.

Verbose levels are:

0 : print nothing
1 : print initial and final defect and statistics
2 : print line for each iteration
