hp::DoFHandler< dim, spacedim >::DoFHandler | ( | const Triangulation< dim, spacedim > & | tria | ) |
Constructor. Take tria
as the triangulation to work on.
virtual hp::DoFHandler< dim, spacedim >::~DoFHandler | ( | ) | [virtual] |
Destructor.
hp::DoFHandler< dim, spacedim >::DoFHandler | ( | const DoFHandler< dim, spacedim > & | ) | [private] |
Copy constructor. I can see no reason why someone might want to use it, so I don't provide it. Since this class has pointer members, making it private prevents the compiler to provide it's own, incorrect one if anyone chose to copy such an object.
virtual void hp::DoFHandler< dim, spacedim >::distribute_dofs | ( | const hp::FECollection< dim, spacedim > & | fe | ) | [virtual] |
Go through the triangulation and distribute the degrees of freedoms needed for the given finite element according to the given distribution method.
A pointer of the transferred finite element is stored. Therefore, the lifetime of the finite element object shall be longer than that of this object. If you don't want this behaviour, you may want to call the clear
member function which also releases the lock of this object to the finite element.
virtual void hp::DoFHandler< dim, spacedim >::clear | ( | ) | [virtual] |
Clear all data of this object and especially delete the lock this object has to the finite element used the last time when distribute_dofs
was called.
void hp::DoFHandler< dim, spacedim >::renumber_dofs | ( | const std::vector< unsigned int > & | new_numbers | ) |
Renumber degrees of freedom based on a list of new dof numbers for all the dofs.
new_numbers
is an array of integers with size equal to the number of dofs on the present grid. It stores the new indices after renumbering in the order of the old indices.
This function is called by the functions in DoFRenumbering function after computing the ordering of the degrees of freedom. However, you can call this function yourself, which is necessary if a user wants to implement an ordering scheme herself, for example downwind numbering.
The new_number
array must have a size equal to the number of degrees of freedom. Each entry must state the new global DoF number of the degree of freedom referenced.
unsigned int hp::DoFHandler< dim, spacedim >::max_couplings_between_dofs | ( | ) | const |
Return the maximum number of degrees of freedom a degree of freedom in the given triangulation with the given finite element may couple with. This is the maximum number of entries per line in the system matrix; this information can therefore be used upon construction of the SparsityPattern object.
The returned number is not really the maximum number but an estimate based on the finite element and the maximum number of cells meeting at a vertex. The number holds for the constrained matrix also.
As for DoFHandler::max_couplings_between_dofs(), the result of this function is often not very accurate for 3d and/or high polynomial degrees. The consequences are discussed in the documentation of the module on Sparsity patterns.
unsigned int hp::DoFHandler< dim, spacedim >::max_couplings_between_boundary_dofs | ( | ) | const |
Return the number of degrees of freedom located on the boundary another dof on the boundary can couple with.

in one dimension less.

in 2D.

Free all used memory.
void hp::DoFHandler< dim, spacedim >::create_active_fe_table | ( | ) | [private] |
Create default tables for the active_fe_indices in the internal::hp::DoFLevels. They are initialized with the a zero indicator, meaning that fe[0] is going to be used by default.

Compute identities between DoFs located on quads. Called from distribute_dofs().
void hp::DoFHandler< dim, spacedim >::renumber_dofs_internal | ( | const std::vector< unsigned int > & | new_numbers, | |
internal::int2type< 0 > | ||||
) | [private] |
Renumber the objects with the given and all lower structural dimensions, i.e. renumber vertices by giving a template argument of zero to the int2type argument, lines and vertices with one, etc.
Note that in contrast to the public renumber_dofs() function, these internal functions do not ensure that the new DoFs are contiguously numbered. The function may therefore also be used to assign different DoFs the same number, for example to unify hp DoFs corresponding to different finite elements but co-located on the same entity.

friend class ::DoFAccessor [friend] |
Make accessor objects friends.
friend class ::DoFCellAccessor [friend] |
friend class internal::DoFAccessor::Implementation [friend] |
friend class internal::DoFCellAccessor::Implementation [friend] |
friend class internal::hp::DoFLevel [friend] |
Likewise for DoFLevel objects since they need to access the vertex dofs in the functions that set and retrieve vertex dof indices.
friend class internal::hp::DoFObjects [friend] |

const unsigned int hp::DoFHandler< dim, spacedim >::dimension = dim [static] |
Make the dimension available in function templates.
const unsigned int hp::DoFHandler< dim, spacedim >::space_dimension = spacedim [static] |
Make the space dimension available in function templates.
const unsigned int hp::DoFHandler< dim, spacedim >::invalid_dof_index = numbers::invalid_unsigned_int [static] |
When the arrays holding the DoF indices are set up, but before they are filled with actual values, they are set to an invalid value, in order to monitor possible problems. This invalid value is the constant defined here.
Please note that you should not rely on it having a certain value, but rather take its symbolic name.
const unsigned int hp::DoFHandler< dim, spacedim >::default_fe_index = numbers::invalid_unsigned_int [static] |
The default index of the finite element to be used on a given cell. For the usual, non-hp DoFHandler class that only supports the same finite element to be used on all cells, the index of the finite element needs to be the same on all cells anyway, and by convention we pick zero for this value. The situation here is different, since the hp classes support the case where different finite element indices may be used on different cells. The default index consequently corresponds to an invalid value.
SmartPointer<const Triangulation<dim,spacedim> > hp::DoFHandler< dim, spacedim >::tria [protected] |
Address of the triangulation to work on.
SmartPointer<const hp::FECollection<dim,spacedim> > hp::DoFHandler< dim, spacedim >::finite_elements [protected] |
Store a pointer to the finite element set given latest for the distribution of dofs. In order to avoid destruction of the object before the lifetime of the DoF handler, we subscribe to the finite element object. To unlock the FE before the end of the lifetime of this DoF handler, use the clear()
function (this clears all data of this object as well, though).
std::vector<internal::hp::DoFLevel<dim>*> hp::DoFHandler< dim, spacedim >::levels [private] |

tree of the Triangulation objects.

pointer of the Triangulation objects.

Store the number of dofs created last time.
std::vector<unsigned int> hp::DoFHandler< dim, spacedim >::vertex_dofs [private] |
Array to store the indices for degrees of freedom located at vertices.
The format used here, in the form of a linked list, is the same as used for the arrays used in the hp::DoFLevel hierarchy. Starting indices into this array are provided by the vertex_dofs_offsets field.
Access to this field is generally through the DoFAccessor::get_vertex_dof_index() and DoFAccessor::set_vertex_dof_index() functions, encapsulating the actual data format used to the present class.
std::vector<unsigned int> hp::DoFHandler< dim, spacedim >::vertex_dofs_offsets [private] |
For each vertex in the triangulation, store the offset within the vertex_dofs array where the dofs for this vertex start.
As for that array, the format is the same as described in the documentation of hp::DoFLevel.
Access to this field is generally through the Accessor::get_vertex_dof_index() and Accessor::set_vertex_dof_index() functions, encapsulating the actual data format used to the present class.
std::vector<std::vector<bool> *> hp::DoFHandler< dim, spacedim >::has_children [private] |
Array to store the information, if a cell on some level has children or not. It is used by the refinement listeners as a persistent buffer during the refinement.
