Detailed Description

The result is the transpose of RT0 interpolation divided by the product of the refinement ratio. Fine ghost values outside the fine level must be zero. On a physical boundary the weights are normalized to sum to one.

Constructor & Destructor Documentation

◆ CartSideDoubleRT0Coarsen() [1/2]

IBTK::CartSideDoubleRT0Coarsen::CartSideDoubleRT0Coarsen ( SAMRAI::hier::IntVector< NDIM > gcw = SAMRAI::hier::IntVector< NDIM >(1) )

Parameters

gcw	Stencil width: at least the refinement ratio minus one in every direction.

◆ ~CartSideDoubleRT0Coarsen()

IBTK::CartSideDoubleRT0Coarsen::~CartSideDoubleRT0Coarsen ( )

default

◆ CartSideDoubleRT0Coarsen() [2/2]

IBTK::CartSideDoubleRT0Coarsen::CartSideDoubleRT0Coarsen ( const CartSideDoubleRT0Coarsen & from )

privatedelete

Note: This constructor is not implemented and should not be used.

Parameters

from	The value to copy to this object.

Member Function Documentation

◆ findCoarsenOperator() [1/2]

bool IBTK::CartSideDoubleRT0Coarsen::findCoarsenOperator	(	const SAMRAI::tbox::Pointer< SAMRAI::hier::Variable< NDIM >> &	var,
		const std::string &	op_name
	)		const

override

Return true if the coarsening operation matches the variable and name string identifier request; false, otherwise.

◆ getOperatorName()

const std::string& IBTK::CartSideDoubleRT0Coarsen::getOperatorName ( ) const

overridevirtual

Return name string identifier of the coarsening operation.

Implements SAMRAI::xfer::CoarsenOperator< NDIM >.

◆ getOperatorPriority()

int IBTK::CartSideDoubleRT0Coarsen::getOperatorPriority ( ) const

overridevirtual

Return the priority of this operator relative to other coarsening operators. The SAMRAI transfer routines guarantee that coarsening using operators with lower priority will be performed before those with higher priority.

Implements SAMRAI::xfer::CoarsenOperator< NDIM >.

◆ getStencilWidth()

SAMRAI::hier::IntVector<NDIM> IBTK::CartSideDoubleRT0Coarsen::getStencilWidth ( ) const

overridevirtual

Return the stencil width associated with the coarsening operator. The SAMRAI transfer routines guarantee that the source patch will contain sufficient ghost cell data surrounding the interior to satisfy the stencil width requirements for each coarsening operator.

Implements SAMRAI::xfer::CoarsenOperator< NDIM >.

◆ coarsen() [1/2]

void IBTK::CartSideDoubleRT0Coarsen::coarsen	(	SAMRAI::hier::Patch< NDIM > &	coarse,
		const SAMRAI::hier::Patch< NDIM > &	fine,
		int	dst_component,
		int	src_component,
		const SAMRAI::hier::Box< NDIM > &	coarse_box,
		const SAMRAI::hier::IntVector< NDIM > &	ratio
	)		const

override

Coarsen the source component on the fine patch to the destination component on the coarse patch. The coarsening operation is performed on the intersection of the destination patch and the coarse box. The fine patch is guaranteed to contain sufficient data for the stencil width of the coarsening operator.

◆ operator=()

CartSideDoubleRT0Coarsen& IBTK::CartSideDoubleRT0Coarsen::operator= ( const CartSideDoubleRT0Coarsen & that )

privatedelete

Note: This operator is not implemented and should not be used.

Parameters

that	The value to assign to this object.

Returns: A reference to this object.

◆ findCoarsenOperator() [2/2]

virtual bool SAMRAI::xfer::CoarsenOperator< DIM >::findCoarsenOperator	(	const tbox::Pointer< hier::Variable< DIM > > &	var,
		const std::string &	op_name
	)		const

pure virtualinherited

Return true if the coarsening operation matches the variable and name string identifier request; false, otherwise.

◆ coarsen() [2/2]

virtual void SAMRAI::xfer::CoarsenOperator< DIM >::coarsen	(	hier::Patch< DIM > &	coarse,
		const hier::Patch< DIM > &	fine,
		const int	dst_component,
		const int	src_component,
		const hier::Box< DIM > &	coarse_box,
		const hier::IntVector< DIM > &	ratio
	)		const

pure virtualinherited

Coarsen the source component on the fine patch to the destination component on the coarse patch. The coarsening operation is performed on the intersection of the destination patch and the coarse box. The fine patch is guaranteed to contain sufficient data for the stencil width of the coarsening operator.

The operator name.

◆ d_gcw

SAMRAI::hier::IntVector<NDIM> IBTK::CartSideDoubleRT0Coarsen::d_gcw
