Detailed Description

Facility for calculating volume-weighted average function values over user-defined regions in parallel.

Defaults to phase-filled pore-volume averages, but falls back to simple pore-volume averages if the saturation is identically zero in a region–i.e., calculates what the average value would be if the phase fully occupied the available pore-volume in this case.

Constructor & Destructor Documentation

RegionPhasePoreVolAverage()

Opm::RegionPhasePoreVolAverage::RegionPhasePoreVolAverage ( const Parallel::Communication & comm, std::size_t numPhases, const std::vector< std::string > & regionNames, RegionArrayAccessor getRegionArray )

explicit

Constructor.

Parameters

[in]	comm	Grid level global communicator.
[in]	numPhases	Number of phases for which to calculate average values.
[in]	regionNames	List of region sets. Typically contains one or more of the FIP* array names and, possibly, the PVTNUM region set as well.
[in]	getRegionArray	Call-back function for accessing region definition from region set names.

Member Function Documentation

accumulateParallel()

void Opm::RegionPhasePoreVolAverage::accumulateParallel

(

)

Accumulate region-level average values across MPI ranks.

Typically the last step in calculating the region-level average values. It is typically an error to call this function multiple times without an intervening call to prepareAccumulation().

addCell()

void Opm::RegionPhasePoreVolAverage::addCell	(	std::size_t	activeCell,
		const Phase &	p,
		const CellValue &	cv )

Incorporate contributions from a single cell.

Parameters

[in]	activeCell	Per-rank active cell ID–typically one of the rank's interior cells.
[in]	p	Phase for which to incorporate the per-cell contribution.
[in]	cv	Single cell function value contribution.

fieldValue()

double Opm::RegionPhasePoreVolAverage::fieldValue

(

const Phase &

p

)

const

Retrieve field-level average function value for specific phase.

Parameters

[in]

p

Phase for which to retrieve the field-level average function value.

Returns

Field-level average function value for phase p.

value()

double Opm::RegionPhasePoreVolAverage::value	(	std::string_view	rset,
		const Phase &	p,
		const Region &	r ) const

Retrieve region-level average function value for specific phase in specific region of named region set.

Parameters

[in]	rset	Named region set–e.g., "FIPNUM".
[in]	p	Phase for which to retrieve the region-level average function value.
[in]	r	Region ID for which to retrieve the region-level average function value.

Returns

Region-level average function value.
