Detailed Description

template<typename number = double>
class MeshWorker::Assembler::CellsAndFaces< number >

Compute cell and face contributions of one or several functionals, typically for error estimates. The information in which component the result is stored for a given cell or face is transmitted by its user_index variable. Hence, you need to make sure to set these variables appropriately before using this class.

initialize()

template<typename number >

void MeshWorker::Assembler::CellsAndFaces< number >::initialize ( AnyData &  results, bool  separate_faces = true  )

inline

The initialization function, specifying the results vectors and whether face data should be collected separately.

results should contain two block vectors named "cells" and "faces" (the latter only if separate_faces is true). In each of the two, each block should have equal size and be large enough to accommodate all user indices set in the cells and faces covered by the loop it is used in. Typically, for estimators, this is Triangulation::n_active_cells() and Triangulation::n_faces(), respectively.

The use of BlockVector may seem cumbersome, but it allows us to assemble several functionals at the same time, one in each block. The typical situation for error estimate is just having a single block in each vector.

initialize_info()

template<typename number >

template<class DOFINFO >

void MeshWorker::Assembler::CellsAndFaces< number >::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.

assemble() [1/2]

template<typename number >

template<class DOFINFO >

void MeshWorker::Assembler::CellsAndFaces< number >::assemble ( const DOFINFO &  info )

inline

Assemble the local values into the global vectors.

assemble() [2/2]

template<typename number >

template<class DOFINFO >

void MeshWorker::Assembler::CellsAndFaces< number >::assemble ( const DOFINFO &  info1, const DOFINFO &  info2  )

inline

Assemble both local values into the global vectors.
