Detailed Description

Typedef Documentation

◆ ContainerIndex

template<typename DFBasis , typename VBE , typename CE >

using Dune::PDELab::Experimental::GridFunctionSpace< DFBasis, VBE, CE >::LeafOrdering::Traits::ContainerIndex = PDELab::MultiIndex<std::size_t,1>

The index to access containers with.

The implementation does not support blocking or other forms of multi-indices yet. Therefore the container index type is always a multi-index with one digit, i.e., an integer.

◆ GridFunctionSubSpace

template<typename GFS , typename TreePath >

using Dune::PDELab::GridFunctionSubSpace = typedef gfs::GridFunctionSubSpace<GFS,TreePath>

Non-nesting implementation of GridFunctionSubSpace.

This is the actual implementation of GridFunctionSubSpace. It is based around the idea of performing the mapping from the subspace to the rootspace in a single step using a SubOrdering. As SubOrderings cannot be nested, this class needs some helper functionality that constructs a new GridFunctionSubSpace directly on top of the underlying root GridFunctionSpace if the user attempts to nest GridFunctionSubSpaces. On the other hand, this implementation should render such usage mostly unnecessary, as it is now possible to directly construct a subspace for a given leaf space. If the compiler has support for template aliases, the de-nesting infrastructure will be able to completely remove all traces of nesting, letting the type obtained by nesting two GridFunctionSubSpaces look exactly like the type obtained by constructing a single GridFunctionSubSpace. Alternatively, without template aliases, it is only possible to have the actual implementation be non-nested. In this case, the Dune::PDELab::GridFunctionSubSpace classes will still nest.

Note: This class should always be used as Dune::PDELab::GridFunctionSubSpace. Never attempt to directly use the class Dune::PDELab::gfs::GridFunctionSubSpace!

Template Parameters

GFS	The root GridFunctionSpace.
TreePath	Path from the root GridFunctionSpace to the represented subspace.

◆ OrderingTag

template<typename G , typename L , typename C , typename B , typename O >

typedef O Dune::PDELab::GridFunctionSpaceTraits< G, L, C, B, O >::OrderingTag

tag describing the ordering.

The tag type may contain additional constants and typedefs to control the behavior of the created ordering.

Enumeration Type Documentation

isComposite	True if this grid function space is composed of others.

◆ find()

template<typename DFBasis , typename VBE , typename CE >

const Traits::FiniteElementType& Dune::PDELab::Experimental::GridFunctionSpace< DFBasis, VBE, CE >::Traits::FEM::find ( const typename GridView::template Codim< 0 >::Entity & element ) const

inline

Get local basis functions for entity.

This method makes a few short-cuts. The problem is that dune-functions bases return LocalFiniteElement objects by value, but the method 'find' here hands them out by reference. Therefore, the FiniteElementMap class has to assume ownership of these objects. In principle they can be different for each element. However, storing a LocalFiniteElement for each element can be very expensive. Therefore, we make the simplifying assumption that the basis is such that the LocalFiniteElement type can be inferred from the GeometryType of the element alone. This will work for many interesting case, but it will fail, for example, for p-adaptive or XFEM-type bases.

◆ GridFunctionSpace() [1/4]

template<typename ES , typename FEM , typename CE = NoConstraints, typename B = ISTL::VectorBackend<>, typename O = DefaultLeafOrderingTag>

Dune::PDELab::GridFunctionSpace< ES, FEM, CE, B, O >::GridFunctionSpace	(	typename Traits::EntitySet	entitySet,
		const FEM &	fem,
		const B &	backend = `B()`,
		const OrderingTag &	ordering_tag = `OrderingTag()`
	)

inline

Warning: The entity set internals will be modified according to the finite element map used codimensions; This version of the constructor takes a reference on the fem. Therefore, these objects shall live longer than the grid function space!

◆ interpolate()

template<typename F , typename GFS , typename XG >

void Dune::PDELab::interpolate	(	const F &	f,
		const GFS &	gfs,
		XG &	xg
	)

interpolation from a given grid function

   \code

#include <dune/pdelab/gridfunctionspace/interpolate.hh>

Parameters

f	Function to interpolate from.
gfs	GridFunctionSpace to use for interpoaltion.
xg	Global vector of dofs to interpolate into.

Note: xg needs to be initialized to the correct size, but there is no need to initialize its contents.

Examples: recipe-geometry-grid.cc, recipe-linear-system-assembly.cc, recipe-linear-system-solution-istl.cc, recipe-linear-system-solution-pdelab.cc, and recipe-operator-splitting.cc.

◆ setEntitySet()

template<typename GFS , typename GFSTraits >

void Dune::PDELab::GridFunctionSpaceBase< GFS, GFSTraits >::setEntitySet ( typename Traits::EntitySet entity_set )

inlineprotected

Set the Entity Set object to this grid function space.

The passed entity set will be stored and modified by the grid function space. In case of a tree, all entity sets below an entity blocking tag are expected to be the same, otherwise, the ordering will issue an exception. (e.g. compartments with different function spaces). Additionally, the root node in a grid function space tree may also contain a different partition which will be used in the assembly process (e.g. a union of all entity sets from leaf nodes). If no other entity set was given, the root node will usually take the first leaf node entity set.

Parameters

entity_set An object of the type PartitionViewEntitySet

◆ update() [1/2]

template<typename DFBasis , typename VBE , typename CE >

void Dune::PDELab::Experimental::GridFunctionSpace< DFBasis, VBE, CE >::update ( bool force = false )

inline

\ param force Set to true if the underlying grid has changed (e.g. due to adaptivity) to force an update of the embedded EntitySet.

◆ update() [2/2]

template<typename GFS , typename GFSTraits >

void Dune::PDELab::GridFunctionSpaceBase< GFS, GFSTraits >::update ( bool force = false )

inline

Update the indexing information of the GridFunctionSpace.
