Detailed Description

Note

This coarsen operator requires that the refinement ratio between coarse and fine index spaces is even.

To avoid complicating the interpolation scheme at coarse-fine interfaces, the use of cubic coarsening is restricted to cases where the refinement ratio is at least 4. For refinement ratios less than 4, a warning is emitted and simple weighted averaging is used instead.

from	The value to copy to this object.

Member Function Documentation

findCoarsenOperator() [1/2]

bool IBTK::CartCellDoubleCubicCoarsen::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() [1/2]

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

override

Return name string identifier of the coarsening operation.

getOperatorPriority() [1/2]

int IBTK::CartCellDoubleCubicCoarsen::getOperatorPriority ( ) const

override

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.

getStencilWidth() [1/2]

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

override

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.

coarsen() [1/2]

void IBTK::CartCellDoubleCubicCoarsen::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=()

CartCellDoubleCubicCoarsen& IBTK::CartCellDoubleCubicCoarsen::operator= ( const CartCellDoubleCubicCoarsen &  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.

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.

getOperatorName() [2/2]

virtual const std::string& SAMRAI::xfer::CoarsenOperator< DIM >::getOperatorName

pure virtualinherited

Return name string identifier of the coarsening operation.

getOperatorPriority() [2/2]

virtual int SAMRAI::xfer::CoarsenOperator< DIM >::getOperatorPriority

pure virtualinherited

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.

getStencilWidth() [2/2]

virtual hier::IntVector<DIM> SAMRAI::xfer::CoarsenOperator< DIM >::getStencilWidth

pure virtualinherited

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.

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.
