Detailed Description

Class for prolongation of multigrid residual onto a finer grid.

Note

This class only does constant prolongation. Using Chombos EBMGInterp with piecewise linear (bi/tri-linear) did not improve multigrid convergence.

Constructor & Destructor Documentation

EBMGProlong()

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

noexcept

Full constructor. Calls the define fucntion.

Parameters

[in]	a_eblgFine	Fine level that we prolong to.
[in]	a_eblgCoar	Coarse level that we prolong from.
[in]	a_refRat	Refinement factor between levels.

Member Function Documentation

define()

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

virtualnoexcept

Define function.

Parameters

[in]	a_eblgFine	Fine level that we prolong to.
[in]	a_eblgCoar	Coarse level that we prolong from.
[in]	a_refRat	Refinement factor between levels.

prolongResidual()

void EBMGProlong::prolongResidual ( LevelData< EBCellFAB > &  a_fineData, const LevelData< EBCellFAB > &  a_coarData, const Interval  a_variables  ) const

virtualnoexcept

Prolong residual onto the coarse grid.

Parameters

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

Member Data Documentation

m_prolongStencils

LayoutData<BaseIVFAB<VoFStencil> > EBMGProlong::m_prolongStencils

protected

Prolongion stencils near the EB.

The stencils are defined on the fine grid but their vofs reach into the coarse grid.
