Detailed Description

template<int DIM>
class SAMRAI::pdat::OuternodeDoubleConstantCoarsen< DIM >

It is derived from the xfer::CoarsenOperator base class. The numerical operations for the averaging use FORTRAN numerical routines.

The findCoarsenOperator() operator function returns true if the input variable is outernode-centered double, and the string is "CONSTANT_COARSEN".

◆ findCoarsenOperator()

template<int DIM>

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

virtual

Returns: True if the variable and name string match the outernode-centered constant averaging; otherwise, return false.

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

◆ getOperatorName()

template<int DIM>

const std::string& SAMRAI::pdat::OuternodeDoubleConstantCoarsen< DIM >::getOperatorName ( ) const

virtual

Returns: descriptive name string identifier of this coarsening operator.

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

◆ getOperatorPriority()

template<int DIM>

int SAMRAI::pdat::OuternodeDoubleConstantCoarsen< DIM >::getOperatorPriority ( ) const

virtual

The priority of outernode-centered constant averaging is 0. It will be performed before any user-defined coarsen operations.

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

◆ getStencilWidth()

template<int DIM>

hier::IntVector<DIM> SAMRAI::pdat::OuternodeDoubleConstantCoarsen< DIM >::getStencilWidth ( ) const

virtual

The stencil width of the constant averaging operator is the vector of zeros. That is, its stencil does not extend outside the fine box.

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

◆ coarsen()

template<int DIM>

void SAMRAI::pdat::OuternodeDoubleConstantCoarsen< 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

virtual

Coarsening is performed on the intersection of the destination patch and the coarse box. It is assumed that the fine patch contains sufficient data for the stencil width of the coarsening operator.

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