Detailed Description

template<typename VectorType>
class MeshWorker::Assembler::ResidualSimple< VectorType >

Assemble residuals without block structure.

The data structure for this Assembler class is a simple vector on each cell with entries from zero to FiniteElementData::dofs_per_cell and a simple global vector with entries numbered from zero to DoFHandler::n_dofs(). No BlockInfo is required and the global vector may be any type of vector having element access through operator() (unsigned int)

Member Function Documentation

◆ initialize() [1/2]

template<typename VectorType >
void MeshWorker::Assembler::ResidualSimple< VectorType >::initialize ( AnyData results)
inline

Initialize with an AnyData object holding the result of assembling.

Assembling currently writes into the first vector of results.

Definition at line 529 of file simple.h.

◆ initialize() [2/2]

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

Initialize the constraints.

Definition at line 536 of file simple.h.

◆ initialize_local_blocks()

template<typename MatrixType >
void MeshWorker::Assembler::ResidualSimple< MatrixType >::initialize_local_blocks ( const BlockIndices )
inline

Store information on the local block structure. If the assembler is initialized with this function, initialize_info() will generate one local matrix for each block row and column, which will be numbered lexicographically, row by row.

In spite of using local block structure, all blocks will be entered into the same global matrix, disregarding any global block structure.

Definition at line 545 of file simple.h.

◆ initialize_info()

template<typename VectorType >
template<class DOFINFO >
void MeshWorker::Assembler::ResidualSimple< 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 552 of file simple.h.

◆ assemble() [1/2]

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

Assemble the local residuals into the global residuals.

Values are added to the previous contents. If constraints are active, AffineConstraints::distribute_local_to_global() is used.

Definition at line 561 of file simple.h.

◆ assemble() [2/2]

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

Assemble both local residuals into the global residuals.

Definition at line 585 of file simple.h.

Member Data Documentation

◆ residuals

template<typename VectorType>
AnyData MeshWorker::Assembler::ResidualSimple< VectorType >::residuals
protected

The global residual vectors filled by assemble().

Definition at line 126 of file simple.h.

◆ constraints

template<typename VectorType>
SmartPointer<const AffineConstraints<typename VectorType::value_type>, ResidualSimple<VectorType> > MeshWorker::Assembler::ResidualSimple< VectorType >::constraints
protected

A pointer to the object containing constraints.
