Detailed Description

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

The fast DG local assembler engine for DUNE grids which assembles the jacobian matrix.

Template Parameters
LAThe local assembler

Constructor & Destructor Documentation

◆ FastDGLocalJacobianAssemblerEngine() [1/2]

template<typename LA >
Dune::PDELab::FastDGLocalJacobianAssemblerEngine< LA >::FastDGLocalJacobianAssemblerEngine ( const LocalAssembler local_assembler_)
inline

Constructor.

Parameters
[in]local_assembler_The local assembler object which creates this engine

◆ FastDGLocalJacobianAssemblerEngine() [2/2]

template<typename LA >
Dune::PDELab::FastDGLocalJacobianAssemblerEngine< LA >::FastDGLocalJacobianAssemblerEngine ( const FastDGLocalJacobianAssemblerEngine< 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.

Member Function Documentation

◆ loadCoefficientsLFSUInside()

template<typename LA >
template<typename LFSUC >
void Dune::PDELab::FastDGLocalJacobianAssemblerEngine< LA >::loadCoefficientsLFSUInside ( const LFSUC &  lfsu_cache)
inline

Methods for loading of the local function's coefficients

◆ onBindLFSUV()

template<typename LA >
template<typename EG , typename LFSUC , typename LFSVC >
void Dune::PDELab::FastDGLocalJacobianAssemblerEngine< LA >::onBindLFSUV ( const EG &  eg,
const LFSUC &  lfsu_cache,
const LFSVC &  lfsv_cache 
)
inline

Called immediately after binding of local function space in global assembler.

const LFSUC &  lfsu_cache,
const LFSVC &  lfsv_cache 
)
inline

Called when the local function space is about to be rebound or discarded

Notifier functions, called immediately before and after assembling

◆ requireSkeleton()

template<typename LA >
bool Dune::PDELab::FastDGLocalJacobianAssemblerEngine< LA >::requireSkeleton ( ) const
inline

Query methods for the global grid assembler

◆ setJacobian()

template<typename LA >
void Dune::PDELab::FastDGLocalJacobianAssemblerEngine< LA >::setJacobian ( Jacobian jacobian_)
inline

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

Referenced by Dune::PDELab::FastDGLocalAssembler< GO, LOP, nonoverlapping_mode >::localJacobianAssemblerEngine().

◆ setSolution()

template<typename LA >
void Dune::PDELab::FastDGLocalJacobianAssemblerEngine< LA >::setSolution ( const Solution solution_)
inline

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

◆ skipEntity()

template<typename LA >
template<typename EG >
bool Dune::PDELab::FastDGLocalJacobianAssemblerEngine< 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.

◆ skipIntersection()

template<typename LA >
template<typename IG >
bool Dune::PDELab::FastDGLocalJacobianAssemblerEngine< 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.
