Detailed Description

Class CoarsenPatchStrategySet is a utility class that allows multiple SAMRAI::xfer::CoarsenPatchStrategy objects to be employed by a single SAMRAI::xfer::CoarsenSchedule.

Member Function Documentation

getCoarsenOpStencilWidth()

IntVector< NDIM > IBTK::CoarsenPatchStrategySet::getCoarsenOpStencilWidth ( ) const

overridevirtual

Return maximum stencil width needed over all user-defined data coarsening operations. This is needed to determine the correct coarsening data dependencies.

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

postprocessCoarsen()

void IBTK::CoarsenPatchStrategySet::postprocessCoarsen ( SAMRAI::hier::Patch< NDIM > &  coarse, const SAMRAI::hier::Patch< NDIM > &  fine, const SAMRAI::hier::Box< NDIM > &  coarse_box, const SAMRAI::hier::IntVector< NDIM > &  ratio  )

overridevirtual

Perform user-defined coarsening operations. This member function is called after standard coarsening operations (expressed using concrete subclasses of the SAMRAI::xfer::CoarsenOperator base class). The postprocess function moves data from the source components on the fine patch into the source components on the coarse patch in the specified coarse box region. Recall that the source components are specified in calls to the registerCoarsen() function in the SAMRAI::xfer::CoarsenAlgorithm class.

Parameters

coarse	Coarse patch containing destination data.
fine	Fine patch containing source data.
coarse_box	Box region on coarse patch into which data is copied.
ratio	Integer vector containing ratio

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

preprocessCoarsen()

void IBTK::CoarsenPatchStrategySet::preprocessCoarsen ( SAMRAI::hier::Patch< NDIM > &  coarse, const SAMRAI::hier::Patch< NDIM > &  fine, const SAMRAI::hier::Box< NDIM > &  coarse_box, const SAMRAI::hier::IntVector< NDIM > &  ratio  )

overridevirtual

Perform user-defined coarsening operations. This member function is called before standard coarsening operations (expressed using concrete subclasses of the SAMRAI::xfer::CoarsenOperator base class). The preprocess function moves data from the source components on the fine patch into the source components on the coarse patch in the specified coarse box region. Recall that the source components are specified in calls to the registerCoarsen() function in the SAMRAI::xfer::CoarsenAlgorithm class.

Parameters

coarse	Coarse patch containing destination data.
fine	Fine patch containing source data.
coarse_box	Box region on coarse patch into which data is coarsened.
ratio	Integer vector containing ratio relating index space between coarse and fine patches.

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