DomainSolver objects are responsible for performing the numerical operations required for the domain decomposition methods.

Constructor & Destructor Documentation

§ DomainSolver()

XC::DomainSolver::DomainSolver ( int classTag )

protected

Constructor.

Parameters

classTag identifier of the class.

Member Function Documentation

§ condenseA()

virtual int XC::DomainSolver::condenseA ( int numInt )

pure virtual

Causes the condenser to form \(A_{ee}^* = A_{ee} -A_{ei} A_{ii}^{-1} A_{ie}\), where \(A_{ii}\) is the first numInt rows of the \(A\) matrix.

The original \(A\) is changed as a result. \(A_{ee}^*\) is to be stored in \(A_{ee}\).

Implemented in XC::ProfileSPDLinSubstrSolver.

§ condenseRHS()

virtual int XC::DomainSolver::condenseRHS	(	int	numInt,
		Vector *	u = `nullptr`
	)

pure virtual

Causes the condenser to form \(B_e^* = B_e - A_{ei} A_{ii}^{-1} B_i\), where \(A_{ii}\) is the first numInt rows of \(A\).

The original \(B\) is changed as a result. \(B_e^*\) is to be stored in \(B_e\).

Implemented in XC::ProfileSPDLinSubstrSolver.

§ getCondensedMatVect()

virtual const Vector& XC::DomainSolver::getCondensedMatVect ( void )

pure virtual

Returns the contents of the last call to {computeCondensedMatVect()}.

Implemented in XC::ProfileSPDLinSubstrSolver.

§ setComputedXext()

virtual int XC::DomainSolver::setComputedXext ( const Vector & )

pure virtual

Sets the computed value of the unknowns in \(X_e\) corresponding to the external equations to u.

The number of external equations is given by the size of vector \(u\).

Implemented in XC::ProfileSPDLinSubstrSolver.

§ solveXint()

virtual int XC::DomainSolver::solveXint ( void )

pure virtual

To compute the internal equation numbers \(X_i\) given the value set for the external equations in the last call to setComputedXext().

Implemented in XC::ProfileSPDLinSubstrSolver.
