Detailed Description

Epetra Finite-Element CrsGraph.

This class provides the ability to insert indices into a matrix-graph, where the indices represent dense submatrices such as element-stiffnesses that might arise from a finite-element application.

In a parallel setting, indices may be submitted on the local processor for rows that do not reside in the local portion of the row-map. After all indices have been submitted, the GlobalAssemble method gathers all non-local graph rows to the appropriate 'owning' processors (an owning processor is a processor which has the row in its row-map).

Member Function Documentation

int Epetra_FECrsGraph::InsertGlobalIndices	(	int	numRows,
		const int *	rows,
		int	numCols,
		const int *	cols
	)

Insert a rectangular, dense 'submatrix' of entries (matrix nonzero positions) into the graph.

Parameters

numRows	Number of rows in the submatrix.
rows	List of row-numbers for the submatrix.
numCols	Number of columns in the submatrix.
cols	List of column-indices that will be used for each row in the 'rows' list.

int Epetra_FECrsGraph::GlobalAssemble ( bool callFillComplete = true )

Gather any overlapping/shared data into the non-overlapping partitioning defined by the Map that was passed to this matrix at construction time.

Data imported from other processors is stored on the owning processor with a "sumInto" or accumulate operation. This is a collective method – every processor must enter it before any will complete it.

NOTE***: When GlobalAssemble() calls FillComplete(), it passes the arguments 'DomainMap()' and 'RangeMap()', which are the map attributes held by the base-class CrsMatrix and its graph. If a rectangular matrix is being assembled, the domain-map and range-map must be specified by calling the other overloading of this method. Otherwise, GlobalAssemble() has no way of knowing what these maps should really be.

Parameters

callFillComplete option argument, defaults to true. Determines whether GlobalAssemble() internally calls the FillComplete() method on this matrix.

Returns: error-code 0 if successful, non-zero if some error occurs

int Epetra_FECrsGraph::GlobalAssemble	(	const Epetra_Map &	domain_map,
		const Epetra_Map &	range_map,
		bool	callFillComplete = `true`
	)

Gather any overlapping/shared data into the non-overlapping partitioning defined by the Map that was passed to this matrix at construction time.

Data imported from other processors is stored on the owning processor with a "sumInto" or accumulate operation. This is a collective method – every processor must enter it before any will complete it.

NOTE***: When GlobalAssemble() (the other overloading of this method) calls FillComplete(), it passes the arguments 'DomainMap()' and 'RangeMap()', which are the map attributes already held by the base-class CrsMatrix and its graph. If a rectangular matrix is being assembled, the domain-map and range-map must be specified. Otherwise, GlobalAssemble() has no way of knowing what these maps should really be.

Parameters

domain_map	user-supplied domain map for this matrix
range_map	user-supplied range map for this matrix
callFillComplete	option argument, defaults to true. Determines whether GlobalAssemble() internally calls the FillComplete() method on this matrix.

Returns: error-code 0 if successful, non-zero if some error occurs
