Detailed Description

template<int dim>
class internal::DoFHandlerImplementation::DoFObjects< dim >

Store the indices of the degrees of freedom which are located on objects of dimension dim.

Information for all DoFObjects classes

The DoFObjects classes store the global indices of the degrees of freedom for each cell on a certain level. The global index or number of a degree of freedom is the zero-based index of the according value in the solution vector and the row and column index in the global matrix or the multigrid matrix for this level. These indices refer to the unconstrained vectors and matrices, where we have not taken account of the constraints introduced by hanging nodes.

Since vertices are not associated with a particular level, the indices associated with vertices are not stored in the DoFObjects classes but rather in the DoFHandler::vertex_dofs array.

The DoFObjects classes are not used directly, but objects of these classes are included in the DoFLevel and DoFFaces classes.

Member Function Documentation

access_dof_index()

template<int dim>

template<int dh_dim, int spacedim>

types::global_dof_index & internal::DoFHandlerImplementation::DoFObjects< dim >::access_dof_index ( const DoFHandler< dh_dim, spacedim > & dof_handler, const unsigned int obj_index, const types::fe_index fe_index, const unsigned int local_index )

inline

Return the global index of the local_index-th degree of freedom located on the object with number obj_index. The dof_handler argument is used to access the finite element that is to be used to compute the location where this data is stored.

The third argument, fe_index, must equal zero. It is otherwise unused, but we retain the argument so that we can use the same interface for non-hp- and hp-finite element methods, in effect making it possible to share the DoFAccessor class hierarchy between hp- and non-hp-classes.

n_active_fe_indices()

template<int dim>

template<int dh_dim, int spacedim>

unsigned int internal::DoFHandlerImplementation::DoFObjects< dim >::n_active_fe_indices ( const DoFHandler< dh_dim, spacedim > & dof_handler, const types::global_dof_index index ) const

inline

Return the value 1. The meaning of this function becomes clear by looking at what the corresponding functions in the classes internal::hp::DoFObjects

Definition at line 147 of file dof_objects.h.

fe_index_is_active()

template<int dim>

template<int dh_dim, int spacedim>

bool internal::DoFHandlerImplementation::DoFObjects< dim >::fe_index_is_active ( const DoFHandler< dh_dim, spacedim > & dof_handler, const types::global_dof_index index, const types::fe_index fe_index ) const

inline

Similar to the function above. Assert that the given index is zero, and then return true.

memory_consumption()

template<int dim>

std::size_t internal::DoFHandlerImplementation::DoFObjects< dim >::memory_consumption

(

)

const

Determine an estimate for the memory consumption (in bytes) of this object.

serialize()

template<int dim>

template<class Archive >

void internal::DoFHandlerImplementation::DoFObjects< dim >::serialize	(	Archive &	ar,
		const unsigned int	version )
