Detailed Description

template<class T>
class MergeSolver< T >

Elliptic solver using the BiCGStab algorithm that turns the bottom solve into a single grid and solves on one processor if it can.

Member Function Documentation

template<class T>

virtual void MergeSolver< T >::setHomogeneous

(

bool

a_homogeneous

)

[inline, virtual]

reset whether the solver is homogeneous.

Reimplemented from BiCGStabSolver< LevelData< T > >.

template<class T>

virtual void MergeSolver< T >::define	(	LinearOp< LevelData< T > > *	a_op,
		bool	a_homogeneous = false
	)			[inline, virtual]

define the solver. a_op is the linear operator. a_homogeneous is whether the solver uses homogeneous boundary conditions.

Reimplemented from BiCGStabSolver< LevelData< T > >.

template<class T>

virtual void MergeSolver< T >::setConvergenceMetrics	(	Real	a_metric,
		Real	a_tolerance
	)			[inline, virtual]

Set a convergence metric, along with solver tolerance, if desired.

Default implementation does nothing, since there are probably cases (liked direct solves), where this has no real meaning.

Reimplemented from BiCGStabSolver< LevelData< T > >.

template<class T>

void MergeSolver< T >::solve	(	LevelData< T > &	a_phi,
		const LevelData< T > &	a_rhs
	)			[inline, virtual]

only overridden virtual function

Reimplemented from BiCGStabSolver< LevelData< T > >.
