assembleInteriorIntersectionMatrix()

template<Concepts::LocalView RowLocalView, Concepts::LocalView ColLocalView>

template<Concepts::BlockMatrix LocalMatrices>

void Dune::Assembler::Concepts::Archetypes::LocalInteriorIntersectionMatrixAssembler< RowLocalView, ColLocalView >::assembleInteriorIntersectionMatrix ( const Intersection &  is, LocalMatrices &  m  )

noexcept

The matrix m is a 2x2 block-matrix for [ii, io; oi, oo] couplings with i...inside and o...outside. Each submatrixm[i][j]` is assumed to be large enough to be indexable by all corresponding inside/outside local view indices. It is not guaranteed that the submatrices havae the exact size as the local views. It is not allowed to resize the submatrices. The matrix is initialized and the assembler must only add its contributions to the matrix and not replace values.

Parameters

is	An intersection to assembler the local matrix on.
m	A 2x2 block-matrix to be filled with the local element contributions.

Note

The local assembler implementation should allow flexible matrix types as argument.

This function is called for all interior intersections. It is not called for domain or processor boundary intersections unless this assembler is also a boundary intersection assembler.

The user might check is.neighbor()

The outside element is accessible via is.outside

The inside element is equal to the element the assembler was bound to in bindElement().

[[pre: m.rows() == 2 && m.cols() == 2]] [[pre: m[0][0].rows() == rowLocalView.size() && m[0][0].cols() == colLocalView.size()]] [[pre: m[0][1].rows() == rowLocalView.size() && m[0][1].cols() == outsideColLocalView.size()]] [[pre: m[1][0].rows() == outsideRowLocalView.size() && m[1][0].cols() == colLocalView.size()]] [[pre: m[1][1].rows() == outsideRowLocalView.size() && m[1][1].cols() == outsideColLocalView.size()]] [[pre: bindElement was called before with current element]]

assembleInteriorIntersectionMatrixPattern()

template<Concepts::LocalView RowLocalView, Concepts::LocalView ColLocalView>

template<Concepts::BlockLocalMatrixPattern LocalPatterns>

void Dune::Assembler::Concepts::Archetypes::LocalInteriorIntersectionMatrixAssembler< RowLocalView, ColLocalView >::assembleInteriorIntersectionMatrixPattern ( const Intersection &  is, LocalPatterns &  p  )

noexcept

Similar as assembleInteriorIntersectionMatrix but the 2x2 block matrix contains local patterns. Each local pattern can be accessed by p[i][j].add(row,col). Additionally, it is possible to set a local pattern to be full, by p[i][j].addAll().

bindElement()

template<Concepts::LocalView RowLocalView, Concepts::LocalView ColLocalView>

void Dune::Assembler::Concepts::Archetypes::LocalInteriorIntersectionMatrixAssembler< RowLocalView, ColLocalView >::bindElement ( const Element &  e )

noexcept

When this function is called, the test and trial local views are already bound to this element. The lifetime of the passed element is longer than the lifetime of the local assembler.

Parameters

e	Grid element the local assembler can be bound to.

Note

The user might check e.hasBoundaryIntersections()

[[pre: rowLocalView.bound() && colLocalView.bound()]]

bindLocalViews()

template<Concepts::LocalView RowLocalView, Concepts::LocalView ColLocalView>

void Dune::Assembler::Concepts::Archetypes::LocalInteriorIntersectionMatrixAssembler< RowLocalView, ColLocalView >::bindLocalViews ( const RowLocalView &  rlv, const ColLocalView &  clv  )

noexcept

This function is called typically before the elements of the grid are traversed. Thus, the local views are not necessarily bound to any element. The lifetime of the passed local view is longer than the lifetime of the local assembler.

Parameters

rlv	A local view of the test space
clv	A local view of the trial space

bindOutsideLocalViews()

template<Concepts::LocalView RowLocalView, Concepts::LocalView ColLocalView>

void Dune::Assembler::Concepts::Archetypes::LocalInteriorIntersectionMatrixAssembler< RowLocalView, ColLocalView >::bindOutsideLocalViews ( const RowLocalView &  rlv, const ColLocalView &  clv  )

noexcept

This function is called typically before the elements of the grid are traversed. Thus, the local views are not necessarily bound to any element. The lifetime of the passed local view is longer than the lifetime of the local assembler.

Parameters

rlv	A local view of the test space that will be bound to an intersection-outside element.
clv	A local view of the trial space that will be bound to an intersection-outside element.
