Detailed Description

template<class T>
class MGLevelOp< T >

class MGLevelOp handles the additional tasks of coordinating operations between this level, and the level one coarser than this 'level'

Member Function Documentation

template<class T>

virtual void MGLevelOp< T >::createCoarser	(	T &	a_coarse,
		const T &	a_fine,
		bool	ghosted
	)			[pure virtual]

Create a coarsened (by two) version of the input data. This does not include averaging the data. So if a_fine is over a Box of (0, 0, 0) (63, 63, 63), a_fine should be over a Box (0, 0, 0) (31, 31, 31).

Implemented in AMRNodeOp, AMRPoissonOp, NewPoissonOp, ResistivityOp, VCAMRPoissonOp, ViscousTensorOp, EBAMRPoissonOp, EBConductivityOp, EBPoissonOp, and EBViscousTensorOp.

template<class T>

virtual void MGLevelOp< T >::relax	(	T &	a_correction,
		const T &	a_residual,
		int	a_iterations
	)			[pure virtual]

Use your relaxtion operator to remove the high frequency wave numbers from the correction so that it may be averaged to a coarser refinement. A point relaxtion scheme, for example takes the form a_correction -= lambda*(L(a_correction) - a_residual).

Implemented in AMRNodeOp, AMRPoissonOp, NewPoissonOp, ResistivityOp, VCAMRPoissonOp, VCAMRPoissonOp2, ViscousTensorOp, EBAMRPoissonOp, EBConductivityOp, EBPoissonOp, and EBViscousTensorOp.

template<class T>

virtual void MGLevelOp< T >::restrictResidual	(	T &	a_resCoarse,
		T &	a_phiFine,
		const T &	a_rhsFine
	)			[pure virtual]

calculate restricted residual a_resCoarse[2h] = I[h->2h] (rhsFine[h] - L[h](phiFine[h])

Implemented in AMRNodeOp, AMRPoissonOp, NewPoissonOp, ResistivityOp, VCAMRPoissonOp, VCAMRPoissonOp2, ViscousTensorOp, EBAMRPoissonOp, EBConductivityOp, EBPoissonOp, and EBViscousTensorOp.

template<class T>

virtual void MGLevelOp< T >::prolongIncrement	(	T &	a_phiThisLevel,
		const T &	a_correctCoarse
	)			[pure virtual]

correct the fine solution based on coarse correction a_phiThisLevel += I[2h->h](a_correctCoarse)

Implemented in AMRNodeOp, AMRPoissonOp, NewPoissonOp, ResistivityOp, VCAMRPoissonOp, ViscousTensorOp, EBAMRPoissonOp, EBConductivityOp, EBPoissonOp, and EBViscousTensorOp.
