Enumeration Type Documentation

Blocking

enum Dune::PDELab::ISTL::Blocking

strong

The type of blocking employed at this node in the function space tree.

Enumerator
none	No blocking at this level.
bcrs	Creates one macro block for each child space, each block is a BlockVector / BCRS matrix.
fixed	Create fixed size blocks that each group together a fixed number of DOFs from each child space. Creates a block structure with fixed size child blocks that each group together a fixed number of DOFs from each child space. Typically used for entity-wise blocking of DOFs across child spaces for e.g. velocity in flow problems or concentrations in multi-component transport. Note This type of blocking cannot be nested due to limitations in ISTL.

Function Documentation

container_tag()

template<typename T >

tags::container<T>::type Dune::PDELab::ISTL::container_tag

(

const T &

)

Gets instance of container tag associated with T.

Returns an instance of the container tag for T. This function is convenient when doing function-based tag dispatch, as it saves on a lot of typing.

Template Parameters

T	The container for which to return a tag.

Returns

An instance of the associated container tag.
