Constructor & Destructor Documentation

SchurApproximation()

template<class OperatorType , class StokesMatrixType , class SchurComplementMatrixType , class VectorType >

aspect::internal::SchurApproximation< OperatorType, StokesMatrixType, SchurComplementMatrixType, VectorType >::SchurApproximation	(	const OperatorType &	schur_preconditioner,
		const StokesMatrixType &	stokes_matrix,
		const SchurComplementMatrixType &	Schur_complement_block,
		const bool	do_solve_Schur_complement,
		const double	Schur_complement_tolerance
	)

Constructor.

Parameters

schur_preconditioner	Preconditioner for the Schur Complement.
stokes_matrix	Stokes system. This is not necessarily a matrix.
Schur_complement_block	Operator for the Schur complement.
do_solve_Schur_complement	Flag that determines whether to do a full solve with the Schur complement or a v-cycle.
Schur_complement_tolerance	Tolerance in case a full solve for the Schur complement is used.
