Detailed Description

template<typename MatrixType>
class MeshWorker::Assembler::MGMatrixSimple< MatrixType >

Assemble local matrices into level matrices without using block structure.

Todo: The matrix structures needed for assembling level matrices with local refinement and continuous elements are missing.

Constructor & Destructor Documentation

◆ MGMatrixSimple()

template<typename MatrixType>

MeshWorker::Assembler::MGMatrixSimple< MatrixType >::MGMatrixSimple ( double threshold = 1.e-12 )

inline

Constructor, initializing the threshold, which limits how small numbers may be to be entered into the matrix.

Definition at line 760 of file simple.h.

Member Function Documentation

◆ initialize() [1/2]

template<typename MatrixType>

void MeshWorker::Assembler::MGMatrixSimple< MatrixType >::initialize ( MGLevelObject< MatrixType > & m )

inline

Store the result matrix for later assembling.

Definition at line 767 of file simple.h.

◆ initialize() [2/2]

template<typename MatrixType>

void MeshWorker::Assembler::MGMatrixSimple< MatrixType >::initialize ( const MGConstrainedDoFs & mg_constrained_dofs )

inline

Initialize the multilevel constraints.

Definition at line 774 of file simple.h.

◆ initialize_fluxes()

template<typename MatrixType>

void MeshWorker::Assembler::MGMatrixSimple< MatrixType >::initialize_fluxes	(	MGLevelObject< MatrixType > &	flux_up,
		MGLevelObject< MatrixType > &	flux_down )

inline

Initialize the matrices flux_up and flux_down used for local refinement with discontinuous Galerkin methods.

Definition at line 782 of file simple.h.

◆ initialize_interfaces()

template<typename MatrixType>

void MeshWorker::Assembler::MGMatrixSimple< MatrixType >::initialize_interfaces	(	MGLevelObject< MatrixType > &	interface_in,

Definition at line 1033 of file simple.h.

◆ assemble() [2/4]

template<typename MatrixType>

template<class DOFINFO>

void MeshWorker::Assembler::MGMatrixSimple< MatrixType >::assemble	(	const DOFINFO &	info1,
		const DOFINFO &	info2 )

inline
