Detailed Description

template<typename MatrixType, typename VectorType>
class MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >

Assemble a simple matrix and a simple right hand side at once. We use a combination of MatrixSimple and ResidualSimple to achieve this. Cell and face operators should fill the matrix and vector objects in LocalResults and this class will assemble them into matrix and vector objects.

Constructor & Destructor Documentation

◆ SystemSimple()

template<typename MatrixType , typename VectorType >
MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::SystemSimple ( double  threshold = 1.e-12)

Constructor setting the threshold value in MatrixSimple.

Member Function Documentation

◆ initialize() [1/2]

template<typename MatrixType , typename VectorType >
void MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::initialize ( MatrixType &  m,
VectorType &  rhs 
)
inline

Store the two objects data is assembled into.

Definition at line 1240 of file simple.h.

◆ initialize() [2/2]

template<typename MatrixType , typename VectorType >
void MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::initialize ( const AffineConstraints< typename VectorType::value_type > &  constraints)
inline

Initialize the constraints. After this function has been called with a valid AffineConstraints object, the function AffineConstraints::distribute_local_to_global() will be used by assemble() to distribute the cell and face matrices into a global sparse matrix.

Definition at line 1253 of file simple.h.

◆ initialize_info()

template<typename MatrixType , typename VectorType >
template<class DOFINFO >
void MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::initialize_info ( DOFINFO &  info,
bool  face 
) const
inline

Initialize the local data in the DoFInfo object used later for assembling.

The info object refers to a cell if !face, or else to an interior or boundary face.

Definition at line 1263 of file simple.h.

◆ assemble() [1/4]

template<typename MatrixType , typename VectorType >
template<class DOFINFO >
void MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::assemble ( const DOFINFO &  info)
inline

Assemble the matrix DoFInfo::M1[0] into the global matrix.

Definition at line 1345 of file simple.h.

◆ assemble() [2/4]

template<typename MatrixType , typename VectorType >
template<class DOFINFO >
void MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::assemble ( const DOFINFO &  info1,
const DOFINFO &  info2 
)
inline

Assemble both local matrices in the info1 and info2 objects into the global matrix.

Definition at line 1390 of file simple.h.

◆ assemble() [3/4]

template<typename MatrixType , typename VectorType >
void MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::assemble ( const FullMatrix< double > &  M,
const Vector< double > &  vector,
const unsigned int  index,
const std::vector< types::global_dof_index > &  indices 
)
inlineprivate

Assemble a single matrix M into the element at index in the vector matrix.

Definition at line 1272 of file simple.h.

◆ assemble() [4/4]

template<typename MatrixType , typename VectorType >
void MeshWorker::Assembler::SystemSimple< MatrixType, VectorType >::assemble ( const FullMatrix< double > &  M,
const Vector< double > &  vector,
const unsigned int  index,
const std::vector< types::global_dof_index > &  i1,
const std::vector< types::global_dof_index > &  i2 
)
inlineprivate
