Detailed Description

A class for handling particle deposition clouds that hang over refinement boundaries. This class does not include any deposition functionality but provides buffers for moving mass between two levels.

To use this class, the user can directly some functions:

addFineGhostsToCoarse which adds the contribution of the fine level's particles to the coarse level. This will add the part of the particle clouds that hang over the refinement boundary to the coarse level. Likewise, the user can get a buffer (getFiCoBuffer) for getting a temporary data holder on which he can use special deposition procedures.
addFiCoDataToFine where the user will have deposited coarse-level particles on a fine-grid buffer, and he/she wants to add the result back to the fine grid.
addInvalidCoarseToFine where the coarse-grid deposition clouds are interpolated to the fine grid. This is the case when e.g. the coarse-grid clouds deposit underneath the fine level but the mass should end up on the fine level.
exchangeAndAddFiCoData where deposited particles on the refined coarse grids have their masses synchronized (ghost cells are added across patches).

EBCoarseFineParticleMesh::EBCoarseFineParticleMesh	(	const EBLevelGrid &	a_eblgCoar,
		const EBLevelGrid &	a_eblgFine,
		const int	a_refRat,
		const IntVect	a_ghost
	)

noexcept

Full constructor. Calls define.

Parameters

[in]	a_eblgFine	Fine grids
[in]	a_refRat	Refinement factory between levels
[in]	a_ghost	Number of ghost cells in mesh data holders.

Member Function Documentation

◆ addFiCoDataToFine()

void EBCoarseFineParticleMesh::addFiCoDataToFine	(	LevelData< EBCellFAB > &	a_fineData,
		const LevelData< EBCellFAB > &	a_fiCoData
	)		const

virtualnoexcept

Add the valid+ghost cells on the refined coarse level to the valid cells on the fine level.

This routine is used when the user have deposited coarse-level particles into a_fiCoData (which is a refinement of the coarse level). This routine then adds that data to the fine level. The motion plan defines the computation region as valid+ghost -> valid, which is what we want.

Parameters

[in,out]	a_fineData	Fine mesh data
[in]	a_fiCoData	Refined coarse data buffer. Users will have deposited the mesh data onto this

◆ addFineGhostsToCoarse()

void EBCoarseFineParticleMesh::addFineGhostsToCoarse	(	LevelData< EBCellFAB > &	a_coarData,
		const LevelData< EBCellFAB > &	a_fineData
	)		const

virtualnoexcept

Coarsen the fine-level ghost cells and add them to the coarse level.

On output, the contents in the ghost cells on the refinement boundary are added from the fine level to the coarse level. This routine is used when the fine-level particles have particle clouds that deposit into the ghost cells outside the fine level, i.e. over the refinement boundary. This routine coarsens that data and adds the mass to the coarse level.

Parameters

[in,out]	a_coarData	Coarse mesh data.
[in]	a_fineData	Fine mesh data.

◆ addInvalidCoarseToFine()

void EBCoarseFineParticleMesh::addInvalidCoarseToFine	(	LevelData< EBCellFAB > &	a_fineData,
		const LevelData< EBCellFAB > &	a_coarData
	)		const

virtualnoexcept

Function which piecewise interpolates the data underneath the fine grid and adds it to the fine grid.

The data-motion plan is to use the valid+ghost cells on the coarse level and add it into the valid region on the fine level. However, the buffers' ghost regions are set to zero so this should only add non-ghosted data between the levels.

Parameters

[in,out]	a_fineData	Fine-level data.
[in]	a_coarData	Coarse-level data.

◆ arithmeticAverageAndAdd()

void EBCoarseFineParticleMesh::arithmeticAverageAndAdd	(	EBCellFAB &	a_coarData,
		const EBCellFAB &	a_fineData,
		const DataIndex &	a_din
	)		const

protectednoexcept

Arithmetically average and add data from the refined coarse data to the coarse data.

Parameters

[in,out]	a_coarData	Coarse-grid data
[in]	a_fineData	Fine-grid data (must be on a refined layout of the coarse grid)
[in]	a_din	Grid idnex

◆ conservativeAverageAndAdd()

void EBCoarseFineParticleMesh::conservativeAverageAndAdd	(	EBCellFAB &	a_coarData,
		const EBCellFAB &	a_fineData,
		const DataIndex &	a_din
	)		const

protectednoexcept

Conservatively average and add data from the refined coarse data to the coarse data.

Parameters

[in,out]	a_coarData	Coarse-grid data
[in]	a_fineData	Fine-grid data (must be on a refined layout of the coarse grid)
[in]	a_din	Grid index

◆ define()

void EBCoarseFineParticleMesh::define	(	const EBLevelGrid &	a_eblgCoar,
		const EBLevelGrid &	a_eblgFine,
		const int	a_refRat,
		const IntVect	a_ghost
	)

virtualnoexcept

Define function.

Parameters

[in]	a_eblgCoar	Coarse grids
[in]	a_eblgFine	Fine grids
[in]	a_refRat	Refinement factory between levels
[in]	a_ghost	Number of ghost cells in mesh data holders.

◆ restrictAndAddFiCoDataToCoar()

void EBCoarseFineParticleMesh::restrictAndAddFiCoDataToCoar	(	LevelData< EBCellFAB > &	a_coarData,
		const LevelData< EBCellFAB > &	a_fiCoData,
		const EBCoarseFineParticleMesh::Average	a_average
	)		const

virtualnoexcept

Coarsen the data on the refined coarse grid to the coarse grid. The grids must be defined over the same layout.

Parameters

[in,out]	a_coarData	Coarse-grid data
[in]	a_fineData	Data on the refined coarse grid
[in]	a_average	Averaging method. Either arithmetic or conservative.

Copier for that moves data from valid+ghost -> valid on the refined coarse level.
