◆ assembleUVBoundary()

template<typename IG , typename LFSU_S , typename LFSV_S >
void Dune::PDELab::LocalAssemblerEngine::assembleUVBoundary ( const IG &  ig,
const LFSU_S &  lfsu_s,
const LFSV_S &  lfsv_s 
)

Assembling for a boundary codim 1 entity part for trial and test local function spaces.

◆ assembleUVProcessor()

template<typename IG , typename LFSU_S , typename LFSV_S >
void Dune::PDELab::LocalAssemblerEngine::assembleUVProcessor ( const IG &  ig,
const LFSU_S &  lfsu_s,
const LFSV_S &  lfsv_s 
)

Assembling for a processor boundary codim 1 entity part for trial and test local function spaces. Specifically, this method will be called for intersections for which it holds that both ig.boundary() and ig.neighbor() return false, i.e. intersections for which it is not possible to obtain the outside entity.

◆ assembleUVSkeleton()

template<typename IG , typename LFSU_S , typename LFSV_S , typename LFSU_N , typename LFSV_N >
void Dune::PDELab::LocalAssemblerEngine::assembleUVSkeleton ( const IG &  ig,

const LFSV_S &  lfsv_s,
const LFSU_N &  lfsu_n,
const LFSV_N &  lfsv_n 
)

Assembling for an interior codim 1 entity part for trial and test local function spaces.

◆ assembleUVVolume()

template<typename EG , typename LFSU , typename LFSV >

Assembling for a codim 0 entity part for trial and test local function spaces.

◆ assembleUVVolumePostSkeleton()

template<typename EG , typename LFSU , typename LFSV >
void Dune::PDELab::LocalAssemblerEngine::assembleUVVolumePostSkeleton ( const EG &  eg,
const LFSU &  lfsu,
const LFSV &  lfsv 
)

Assembling for a codim 0 entity part for trial and test local function spaces which is called after the intersection parts of the current cell have been handled.

◆ assembleVBoundary()

template<typename IG , typename LFSV_S >
void Dune::PDELab::LocalAssemblerEngine::assembleVBoundary ( const IG &  ig,
const LFSV_S &  lfsv_s 
)

Assembling for a boundary codim 1 entity part for test local function spaces.

◆ assembleVProcessor()

template<typename IG , typename LFSV_S >
void Dune::PDELab::LocalAssemblerEngine::assembleVProcessor ( const IG &  ig,
const LFSV_S &  lfsv_s 
)

Assembling for a processor boundary codim 1 entity part for test local function spaces. Specifically, this method will be called for intersections for which it holds that both ig.boundary() and ig.neighbor() return false, i.e. intersections for which it is not possible to obtain the outside entity.

◆ assembleVSkeleton()

template<typename IG , typename LFSV_S , typename LFSV_N >
void Dune::PDELab::LocalAssemblerEngine::assembleVSkeleton ( const IG &  ig,
const LFSV_S &  lfsv_s,
const LFSV_N &  lfsv_n

Assembling for an interior codim 1 entity part for test local function spaces.

void Dune::PDELab::LocalAssemblerEngine::assembleVVolume ( const EG &  eg,
const LFSV &  lfsv 
)

Assembling for a codim 0 entity part for test local function spaces.

◆ assembleVVolumePostSkeleton()

template<typename EG , typename LFSV >
void Dune::PDELab::LocalAssemblerEngine::assembleVVolumePostSkeleton ( const EG &  eg,
const LFSV &  lfsv 
)

Assembling for a codim 0 entity part for test local function spaces which is called after the intersection parts of the current cell have been handled.

◆ skipEntity()

template<typename EG >
bool Dune::PDELab::LocalAssemblerEngine::skipEntity ( const EG &  eg)

Assembling method which is called for a given grid cell. It is called before the local function spaces are bound to the cell and the coefficients for the local trial function space are extracted.

Returns
Indicate whether assembling of this cell may be aborted after the call of this method. This may avoid unneccessary costs due to binding of the local function spaces etc.

◆ skipIntersection()

template<typename IG >
bool Dune::PDELab::LocalAssemblerEngine::skipIntersection ( const IG &  ig)

Assembling method which is called for a given grid intersection. It is called after the cell local function space is bound and before the local function spaces is bound to the outside cell (if any) and similarly for the extraction of the coefficients for the local trial function space.

Returns
Indicate whether assembling of this intersection may be aborted after the call of this method. This may avoid unneccessary costs due to binding of the local function spaces etc.
