Member Function Documentation

assembleBoundaryIntersectionMatrix()

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

template<Concepts::Matrix LocalMatrix>

void Dune::Assembler::Concepts::Archetypes::LocalBoundaryIntersectionMatrixAssembler< RowLocalView, ColLocalView >::assembleBoundaryIntersectionMatrix ( const Intersection &  is, LocalMatrix &  m  )

noexcept

The matrix m is assumed to be large enough to be indexable by all local view indices. It is not guaranteed that the matrix has the exact size as the local views. It is not allowed to resize the matrix. 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 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 domain boundary intersections. It is not called for other inner or processor boundary intersections unless this assembler is also an intersection assembler.

The user might check is.boundary()

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

assembleBoundaryIntersectionMatrixPattern()

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

template<Concepts::LocalMatrixPattern LocalPattern>

void Dune::Assembler::Concepts::Archetypes::LocalBoundaryIntersectionMatrixAssembler< RowLocalView, ColLocalView >::assembleBoundaryIntersectionMatrixPattern ( const Intersection &  is, LocalPattern &  p  )

noexcept

Similar as assembleElementMatrix but for a local pattern instead of a matrix. The local pattern can be accessed by p.add(row,col). Additionally, it is possible to set a local pattern to be full, by p.addAll().

bindElement()

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

void Dune::Assembler::Concepts::Archetypes::LocalBoundaryIntersectionMatrixAssembler< 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

This function is called for all boundary elements. It is not called for inner elements unless this assembler is also an element or intersection assembler.

The user might check e.hasBoundaryIntersections()

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

bindLocalViews()

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

void Dune::Assembler::Concepts::Archetypes::LocalBoundaryIntersectionMatrixAssembler< 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
