◆ LinearSOEData()

XC::LinearSOEData::LinearSOEData	(	SolutionStrategy *	owr,
		int	classTag,
		int	N = `0`
	)

protected

Constructor.

Parameters

owr	analysis aggregation that owns this object.
classTag	identifier of the class.
N	size of the system.

Member Function Documentation

◆ addB() [1/2]

int XC::LinearSOEData::addB	(	const Vector &	v,
		const double &	fact = `1.0`
	)

virtual

add v multiplied by factor to vector B.

Parameters

v	vector to add.
fact	factor that multiplies v.

◆ addB() [2/2]

int XC::LinearSOEData::addB	(	const Vector &	v,
		const ID &	id,
		const double &	fact = `1.0`
	)

virtual

assemblies v multiplied by factor into vector B.

First tests that loc and V are of compatible sizes; if not a warning message is printed and a $-1$ is returned. The LinearSOE object then assembles fact times the Vector V into the vector $b$. The Vector is assembled into $b$ at the locations given by the ID object loc, i.e. $b_{loc(i)} += fact * V(i)$. If a location specified is outside the range, e.g. $-1$, the corresponding entry in V is not added to $b$. If fact is equal to $0.0$, $1.0$ or $-1.0$, more efficient steps are performed. Returns $0$.

Parameters

v	vector to add.
id	row indexes.
fact	factor that multiplies v.

Implements XC::LinearSOE.

Reimplemented in XC::DistributedBandGenLinSOE, XC::DistributedSparseGenColLinSOE, XC::DistributedBandSPDLinSOE, XC::DistributedProfileSPDLinSOE, and XC::SymSparseLinSOE.

◆ inic()

void XC::LinearSOEData::inic ( const size_t & sz )

protected

1d arrays containing coefficients of B and X

Initializes storage.

◆ setB()

int XC::LinearSOEData::setB	(	const XC::Vector &	v,
		const double &	fact = `1.0`
	)

virtual

Sets B= v*fact.

First tests that V and the size of the system are of compatible sizes; if not a warning message is printed and a $-1$ is returned. The LinearSOE object then sets the vector b to be fact times the Vector V. If fact is equal to $0.0$, $1.0$ or $-1.0$, more efficient steps are performed. Returns $0$.

Parameters

v	vector to add.
fact	factor that multiplies v.

Implements XC::LinearSOE.

Reimplemented in XC::DistributedBandGenLinSOE, XC::DistributedSparseGenColLinSOE, XC::DistributedBandSPDLinSOE, and XC::DistributedProfileSPDLinSOE.
