Constructor & Destructor Documentation

◆ NNCCollection() [1/2]

Opm::NNCCollection::NNCCollection ( )

Default constructor: the global grid (grid 0) always exists, initially with an empty NNC container.

◆ NNCCollection() [2/2]

Opm::NNCCollection::NNCCollection ( NNCDataContainer nnc_global )

explicit

Constructs an NNCCollection pre-populated with nnc_global as the global (grid 0) same-grid NNC.

Member Function Documentation

◆ addNNC() [1/3]

void Opm::NNCCollection::addNNC	(	std::size_t	grid1,
		std::size_t	grid2,
		NNCDataContainerDiffGrid	nnc
	)

Add a cross-grid NNC between grid1 and grid2.

Adds a cross-grid NNC between grid1 and grid2.

The key is normalised to (min, max) and cell indices are swapped accordingly. Throws std::runtime_error if an entry for this grid pair already exists.

◆ addNNC() [2/3]

void Opm::NNCCollection::addNNC	(	std::size_t	grid,
		NNCDataContainer	nnc
	)

Add a same-grid NNC for the given grid index.

Adds a same-grid NNC for grid.

For grid 0 (global), replaces the existing empty entry inserted by the constructor. For all other grids, throws std::runtime_error if an entry already exists.

◆ addNNC() [3/3]

void Opm::NNCCollection::addNNC ( NNCDataContainer nnc )

Add the global (main-grid) NNC. Equivalent to addNNC(0, nnc).

Replaces the global (grid 0) same-grid NNC.

◆ empty()

bool Opm::NNCCollection::empty ( ) const

inline

Returns true if the collection holds no NNC data of any kind.

Cannot use m_sameGridNNCs.empty() because grid 0 is always present (inserted by the constructor) even when no NNCs have been added. Instead, each same-grid container is checked for actual entries.

◆ fromLGROutputContainers()

NNCCollection Opm::NNCCollection::fromLGROutputContainers	(	const std::vector< std::vector< NNCdata >> &	outputNnc,
		const std::vector< std::vector< NNCdata >> &	outputNncGlobalLocal,
		const std::vector< std::vector< std::vector< NNCdata >>> &	outputAmalgamatedNnc
	)

static

Build an NNCCollection from the three output containers produced by EclGenericWriter::exportNncStructure_().

Builds an NNCCollection from the three output containers produced by EclGenericWriter::exportNncStructure_().

Parameters

outputNnc	Same-grid NNCs, indexed by grid level. outputNnc[level] holds the NNCs internal to grid `level` (0 = main grid).
outputNncGlobalLocal	Global-to-local NNCs, indexed by local level offset. outputNncGlobalLocal[i] holds connections between the main grid (level 0) and the refined level `i+1`.
outputAmalgamatedNnc	LGR-to-LGR NNCs, indexed by (smallerLevel-1, largerLevel-smallerLevel-1). outputAmalgamatedNnc[i][j] holds connections between level `i+1` and level `i+j+2`.

Returns: An NNCCollection populated with all three NNC types.

Index convention (matches the layout written by exportNncStructure_):

outputNnc[level] → same-grid NNCs for grid level (0 = main grid).

outputNncGlobalLocal[i] → cross-grid NNCs between main grid (level 0) and level i+1.

outputAmalgamatedNnc[i][j] → cross-grid NNCs between level i+1 and level i+j+2.

◆ getGlobalNNC() [1/2]

const NNCDataContainer & Opm::NNCCollection::getGlobalNNC ( ) const

Returns a const reference to the global (grid 0) same-grid NNC.

Grid 0 is always present (inserted by the constructor); never throws.

◆ getGlobalNNC() [2/2]

NNCDataContainer & Opm::NNCCollection::getGlobalNNC ( )

Returns a mutable reference to the global (grid 0) same-grid NNC.

Grid 0 is always present (inserted by the constructor); never throws.

◆ getNNC() [1/2]

const NNCDataContainerDiffGrid & Opm::NNCCollection::getNNC	(	std::size_t	grid1,
		std::size_t	grid2
	)		const

Returns a const reference to the cross-grid NNC for the (grid1, grid2) pair.

Grid order is normalised automatically. Throws std::runtime_error if no entry exists.

◆ getNNC() [2/2]

const NNCDataContainer & Opm::NNCCollection::getNNC ( std::size_t grid ) const

Returns a const reference to the same-grid NNC for grid.

Throws std::runtime_error if no entry exists.

◆ hasGlobalNNC()

bool Opm::NNCCollection::hasGlobalNNC ( ) const

inline

Returns true if the global grid has actual same-grid NNC data.

Grid 0 always exists in the collection; this checks whether it is non-empty (i.e. NNCs were explicitly added for the global grid).

◆ hasNNCForGrid()

bool Opm::NNCCollection::hasNNCForGrid ( std::size_t grid_index ) const

inline

Returns true if the given grid has any NNC involvement: same-grid NNCs with data, or cross-grid NNCs with any other grid.
