Detailed Description

Class for restricting multigrid residual onto a coarser grid.

This class defines an operator for setting phiC = 1/Nref^D * sum(phiFine). This assumes that the input data has already been scaled by the volume fraction (which is what the EB multigrid operators do anyways).

Constructor & Destructor Documentation

EBMGRestrict()

EBMGRestrict::EBMGRestrict ( const EBLevelGrid &  a_eblgFine, const EBLevelGrid &  a_eblgCoar, const int &  a_refRat  )

noexcept

Full constructor. Calls the define function.

Parameters

[in]	a_eblgFine	Fine level
[in]	a_eblgCoar	Coarse level
[in]	a_refRat	Refinement factor between levels.

Member Function Documentation

define()

void EBMGRestrict::define ( const EBLevelGrid &  a_eblgFine, const EBLevelGrid &  a_eblgCoar, const int &  a_refRat  )

virtualnoexcept

Define function.

Parameters

[in]	a_eblgFine	Fine level
[in]	a_eblgCoar	Coarse level
[in]	a_refRat	Refinement factor between levels.

restrictResidual()

void EBMGRestrict::restrictResidual ( LevelData< EBCellFAB > &  a_coarData, const LevelData< EBCellFAB > &  a_fineData, const Interval  a_variables  ) const

virtualnoexcept

Restrict residual onto the coarse grid.

This replaces the coarse-grid residual by an average of the fine-grid residual. Only affects the invalid region of the coarse grid.

Parameters

[in,out]	a_coarData	Coarse-grid residual.
[in]	a_fineData	Fine-grid residual
[in]	a_variables	Variables to restrict

Member Data Documentation

m_restrictStencils

LayoutData<BaseIVFAB<VoFStencil> > EBMGRestrict::m_restrictStencils

protected

Restriction stencils near the EB.

The stencils are defined on the coarse-grid, but reach into the fine grid.
