Detailed Description

template<class GV, class SDPB, class SD>
class Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >

A pre-basis restricted to a sub-domain.

This pre-basis wraps another pre-basis and restricts it to a sub-domain. The wrapped pre-basis is assumed to be defined on a sub-domain of the full grid view. Then the RestrictedPreBasis defines a pre-basis on the full grid view implemented in terms of the pre-basis on the sub-domain. Most of the methods are forwarded to the sub-domain pre-basis with two exceptions: When binding a RestrictedPreBasis::Node, this only calls subDomainNode.bind(element) if the element is contained in the sub-domain, otherwise the sizes of the node and all its descendents is set to zero. Furthermore it only calls subDomainPreBasis.indices(node,it) if node.size() is not zero.

Template Parameters

GV	Type of the (full) grid view this pre-basis is defined on.
SDPB	Type of a pre-basis defined on sub-set of the full grid view
SD	Type of the sub-domain

Constructor & Destructor Documentation

RestrictedPreBasis()

template<class GV , class SDPB , class SD >

Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::RestrictedPreBasis ( const GridView &  gridView, SubDomainPreBasis &&  subDomainPreBasis, const SubDomain &  subDomain  )

inline

Constructor for given sub-domain pre-basis.

The grid view and sub-domain pre-basis will be stored as copy while a pointer to the sub-domain object is stored.

Member Function Documentation

makeNode()

template<class GV , class SDPB , class SD >

Node Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::makeNode ( ) const

inline

Create tree node with given root tree path.

Template Parameters

TP	Type of root tree path

Parameters

tp	Root tree path

By passing a non-trivial root tree path this can be used to create a node suitable for being placed in a tree at the position specified by the root tree path.

update()

template<class GV , class SDPB , class SD >

void Dune::Functions::Experimental::RestrictedPreBasis< GV, SDPB, SD >::update ( const GridView &  gv )

inline

Update the stored grid view, to be called.

This will also call subDomainPreBasis.update(subDomainPtr->gridView()) with the stored sub-domain pointer to update the sub-domain pre-basis. Hence it requires the subDomain object passed to the present pre-basis has been correctly updated externally, before calling this method.
