◆ assemble() [1/2]

int oofem::PetscSparseMtrx::assemble	(	const IntArray &	loc,

Parameters

loc	Location array. The values corresponding to zero loc array value are not assembled.
mat	Contribution to be assembled using loc array.

Returns: Zero iff successful.

Parameters

rloc	Row location array. The values corresponding to zero loc array value are not assembled.
cloc	Column location array. The values corresponding to zero loc array value are not assembled.
mat	Contribution to be assembled using rloc and cloc arrays. The rloc position determines the row, the cloc position determines the corresponding column.

◆ buildInternalStructure() [2/3]

int oofem::PetscSparseMtrx::buildInternalStructure	(	EngngModel *	eModel,
		int	di,
		const UnknownNumberingScheme &	s )

overridevirtual

Builds internal structure of receiver. This method determines the internal profile of sparse matrix, allocates necessary space for storing nonzero coefficients and initializes receiver. In general, the profile of sparse matrix is determined using one (or more) loop over local code numbers of elements. This method must be called before any operation, like assembly, zeroing, or multiplication.

Parameters

eModel	Pointer to corresponding engineering model.
di	Domain index specify which domain to use.
s	Determines unknown numbering scheme.

Returns: Zero iff successful.

Todo: Split this into upper and lower triangular part like for the sequential matrix (we can then use SBAIJ which is a huge performance boost)

Todo: Take into account active boundary conditions here.
