LinearSolver::Tags Namespace Reference

The DataBox tags associated with the linear solver. More...

Classes
struct	MatrixSubfileName
	Subfile name in the volume data H5 files where the matrix will be stored. More...
struct	TotalNumPoints
	Size of the matrix: number of grid points times number of variables. More...
struct	LocalFirstIndex
	Index of the first point in this element. More...
struct	Matrix
	Matrix representation of the linear operator. Stored as sparse matrix. The full matrix has size total_num_points by total_num_points. Each element only stores the rows corresponding to its grid points (starting at local_first_index), but all columns. More...
struct	EnableDirectSolve
	Option for enabling direct solve of the linear problem. More...
struct	SkipResets
	Option for skipping resets of the built matrix. More...
struct	Operand
	The operand that the local linear operator \(A\) is applied to. More...
struct	OperatorAppliedTo
	The linear operator \(A\) applied to the data in Tag. More...
struct	Residual
	The residual \(r=b - Ax\). More...
struct	ResidualCompute
	Compute the residual \(r=b - Ax\) from the SourceTag \(b\) and the db::add_tag_prefix<LinearSolver::Tags::OperatorAppliedTo, FieldsTag> \(Ax\). More...
struct	MagnitudeSquare
	The magnitude square \(\langle \cdot,\cdot\rangle\) w.r.t. the LinearSolver::inner_product. More...
struct	Magnitude
	The magnitude \(\sqrt{\langle \cdot,\cdot\rangle}\) w.r.t. the LinearSolver::inner_product. More...
struct	Orthogonalization
	The prefix for tags related to an orthogonalization procedure. More...
struct	OrthogonalizationHistory
	A Hessenberg matrix built up during an orthogonalization procedure. More...
struct	KrylovSubspaceBasis
	A set of \(n\) vectors that form a basis of the \(n\)-th Krylov subspace \(K_n(A,b)\). More...
struct	Preconditioned
	Indicates the Tag is related to preconditioning of the linear solve. More...
struct	OutputVolumeData
	Whether or not volume data should be recorded for debugging purposes. More...
struct	ObservationId
	Continuously incrementing ID for volume observations. More...
