Detailed Description

template<typename DFBasis, typename VBE, typename CE>
class Dune::PDELab::Experimental::GridFunctionSpace< DFBasis, VBE, CE >

A pdelab grid function space implemented by a dune-functions function space basis.

Warning

This class works only under quite restrictive assumptions:

• The dune-functions basis has to be scalar-valued
• The basis has to be such that the local finite element type for a given element can be infered from the GeometryType of the element alone. (Due to a restriction in the current implementation of the FiniteElementMap)

Template Parameters

DFBasis	A dune-functions function space basis
VBE	The type of the underlying vector backend
CE	Type for constraints assembler

Member Function Documentation

dataHandleSize()

template<typename GFS >

template<typename Entity >

size_type Dune::PDELab::DataHandleProvider< GFS >::dataHandleSize ( const Entity &  e ) const

inlineinherited

how many objects of type DataType have to be sent for a given entity

Note: Only the sender side needs to know this size.

sendLeafSizes()

template<typename GFS >

constexpr bool Dune::PDELab::DataHandleProvider< GFS >::sendLeafSizes ( ) const

inlineconstexprinherited

Returns true if the sizes of the leaf orderings in this tree should be sent as part of the communcation.

The MultiDomain extensions require knowledge about the size of the individual orderings, which might belong to separate subdomains. Otherwise it is possible to have size mismatches for entities with codim > 0 if there are protruding edges in the parallel mesh partitioning.

By default, this method will always return false. It must be overridden for cases where the data actually needs to be sent.

This flag also modifies the behavior of the generic data handles, which will automatically send, receive and process the additional information. Note that if sendLeafSizes() returns true, the underlying DataHandleIF of the grid will always use the data type char to be able to send different types of data, which will automatically be marshalled to / from a byte stream.
