Detailed Description

template<typename LA>
class Dune::PDELab::FastDGLocalResidualAssemblerEngine< LA >

The fast DG local assembler engine for DUNE grids which assembles the residual vector.

Template Parameters

LA	The local assembler

Constructor & Destructor Documentation

◆ FastDGLocalResidualAssemblerEngine() [1/2]

template<typename LA >

Dune::PDELab::FastDGLocalResidualAssemblerEngine< LA >::FastDGLocalResidualAssemblerEngine ( const LocalAssembler & local_assembler_ )

inline

Constructor.

Parameters

[in] local_assembler_ The local assembler object which creates this engine

◆ FastDGLocalResidualAssemblerEngine() [2/2]

template<typename LA >

Dune::PDELab::FastDGLocalResidualAssemblerEngine< LA >::FastDGLocalResidualAssemblerEngine ( const FastDGLocalResidualAssemblerEngine< LA > & other )

inline

copy contructor

Note: This does not create an exact copy. Instead it copies the global views, such that they point to the same global vector. Local matrices/vectors are constructed freshly without copying the content. Views into the local matrices/vectors are constructed freshly so they reference the local matrices/vector in the new object, and are given unit weight. This essentially creates an engine object that is not currently bound to any entity, but otherwise behaves like the object it was contructed from.; This constructor is needed to implement splitting constructors in derived classes.

◆ setResidual()

template<typename LA >

void Dune::PDELab::FastDGLocalResidualAssemblerEngine< LA >::setResidual ( Residual & residual_ )

inline

Set current residual vector. Should be called prior to assembling.

template<typename EG >

bool Dune::PDELab::FastDGLocalResidualAssemblerEngine< LA >::skipEntity ( const EG & eg )

inline

Assembling methods Assemble on a given cell without function spaces.

Returns: If true, the assembling for this cell is assumed to be complete and the assembler continues with the next grid cell.

template<typename IG >

bool Dune::PDELab::FastDGLocalResidualAssemblerEngine< LA >::skipIntersection ( const IG & ig )

inline

Assemble on a given intersection without function spaces.

Returns: If true, the assembling for this intersection is assumed to be complete and the assembler continues with the next grid intersection.
