This class acts as a collection of finite element objects used in the hp::DoFHandler. It is thus to a hp::DoFHandler what a FiniteElement is to a DoFHandler.
It implements the concepts stated in the hp Collections module described in the doxygen documentation.
In addition to offering access to the elements of the collection, this class provides access to the maximal number of degrees of freedom per vertex, line, etc, to allow allocation of as much memory as is necessary in the worst case when using the finite elements associated with the cells of a triangulation.
This class has not yet been implemented for the use in the codimension one case (spacedim != dim
).

hp::FECollection< dim, spacedim >::FECollection  (  ) 
Default constructor. Leads to an empty collection that can later be filled using push_back(). Establishes a hierarchy of finite elements corresponding to their index in the collection.

explicit 
Conversion constructor. This constructor creates a FECollection from a single finite element. More finite element objects can be added with push_back(), if desired, though it would probably be clearer to add all mappings the same way.

Constructor. This constructor creates a FECollection from one or more finite element objects passed to the constructor. For this call to be valid, all arguments need to be of types derived from class FiniteElement<dim,spacedim>.

hp::FECollection< dim, spacedim >::FECollection  (  const std::vector< const FiniteElement< dim, spacedim > *> &  fes  ) 
Constructor. Same as above but for any number of elements. Pointers to the elements are passed in a vector to this constructor. As above, the finite element objects pointed to by the argument are not actually used other than to create copies internally. Consequently, you can delete these pointers immediately again after calling this constructor.

void hp::FECollection< dim, spacedim >::push_back  (  const FiniteElement< dim, spacedim > &  new_fe  ) 
Add a finite element. This function generates a copy of the given element, i.e. you can do things like push_back(FE_Q<dim>(1));
. The internal copy is later destroyed by this object upon destruction of the entire collection.
When a new element is added, it needs to have the same number of vector components as all other elements already in the collection.

Return the number of vector components of the finite elements in this collection. This number must be the same for all elements in the collection.
This function calls FiniteElement::n_components. See the glossary for more information.
Definition at line 853 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::n_blocks  (  )  const 
Return the number of vector blocks of the finite elements in this collection. While this class ensures that all elements stored in it have the same number of vector components, there is no such guarantees for the number of blocks each element is made up of (an element may have fewer blocks than vector components; see the glossary for more information). For example, you may have an FECollection object that stores one copy of an FESystem with dim
FE_Q objects and one copy of an FE_RaviartThomas element. Both have dim
vector components but while the former has dim
blocks the latter has only one. Consequently, this function will throw an assertion if the number of blocks is not the same for all elements. If they are the same, this function returns the result of FiniteElement::n_blocks().
Definition at line 531 of file fe_collection.cc.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_vertex  (  )  const 
Return the maximal number of degrees of freedom per vertex over all elements of this collection.
Definition at line 911 of file fe_collection.h.

unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_hex  (  )  const 
Return the maximal number of degrees of freedom per hex over all elements of this collection.
Definition at line 959 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_face  (  )  const 
Return the maximal number of degrees of freedom per face over all elements of this collection.
Definition at line 975 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_cell  (  )  const 
Return the maximal number of degrees of freedom per cell over all elements of this collection.
Definition at line 991 of file fe_collection.h.
std::size_t hp::FECollection< dim, spacedim >::memory_consumption  (  )  const 
Return an estimate for the memory allocated for this object.
Definition at line 548 of file fe_collection.cc.
bool hp::FECollection< dim, spacedim >::hp_constraints_are_implemented  (  )  const 
Return whether all elements in this collection implement the hanging node constraints in the new way, which has to be used to make elements "hp compatible". If this is not the case, the function returns false, which implies, that at least one element in the FECollection does not support the new face interface constraints. On the other hand, if this method does return true, this does not imply that the hp method will work!
This behaviour is related to the fact, that FiniteElement classes, which provide the new style hanging node constraints might still not provide them for all possible cases. If FE_Q and FE_RaviartThomas elements are included in the FECollection and both properly implement the get_face_interpolation_matrix method, this method will return true. But the get_face_interpolation_matrix might still fail to find an interpolation matrix between these two elements.
Definition at line 1006 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::find_least_face_dominating_fe  (  const std::set< unsigned int > &  fes  )  const 
Try to find a least dominant finite element inside this FECollection which dominates all of those finite elements in the current collection indexed by the numbers provided through fes
. In other words, we first form the set of elements in this collection that dominate all of the ones that are indexed by the argument fes
, and then within that set of dominating elements, we find the least dominant one.
For example, if an FECollection consists of {FE_Q(1),FE_Q(2),FE_Q(3),FE_Q(4)}
elements and the argument fes
equals {2,3}
, then the set of dominating elements consists of {0,1,2}
, of which 2
(i.e., the FE_Q(3)
) is the least dominant one, and then that's what the function returns.
On the other hand, if the FECollection consists of {FE_Q(1)xFE_Q(1),FE_Q(2)xFE_Q(2),FE_Q(2)xFE_Q(3),FE_Q(3)xFE_Q(2)}
elements and the argument is again fes
equal to {2,3}
, then the set of dominating elements consists of {0,1}
because now neither of the last two elements dominates the other, of which 1
(i.e., the FE_Q(2)xFE_Q(2)
) is the least dominant one – so that's what the function returns in this case.
For the purpose of this function by domination we consider either FiniteElementDomination::Domination::this_element_dominates or FiniteElementDomination::Domination::either_element_can_dominate; therefore the element can dominate itself. Thus, if an FECollection contains {FE_Q(1),FE_Q(2),FE_Q(3),FE_Q(4)}
and fes
only has a single element {3}
, then the function returns 3.
If the function is not able to find a finite element that satisfies the description above, the function returns numbers::invalid_unsigned_int. An example would go like this: If the FECollection consists of {FE_Nothing x FE_Nothing, FE_Q(1)xFE_Q(2), FE_Q(2)xFE_Q(1)}
with fes
as {1}
, the function will not find a most dominating element as the default behavior of FE_Nothing is to return FiniteElementDomination::no_requirements when comparing for face domination with any other element. In other words, the set of dominating elements is empty, and we can not find a least dominant one among it. The return value is therefore numbers::invalid_unsigned_int.
hp::FECollection::find_dominating_fe_extended(fes, 1)
. To recreate its exact behavior, use code such as fe_collection.find_dominated_fe( fe_collection.find_common_fes(fes, 1), 1)
. Definition at line 27 of file fe_collection.cc.
std::set< unsigned int > hp::FECollection< dim, spacedim >::find_common_fes  (  const std::set< unsigned int > &  fes, 
const unsigned int  codim = 0 

)  const 
Return the indices of finite elements in this FECollection that dominate all elements associated with the provided set of indices fes
.
You may find information about the domination behavior of finite elements in their respecitve class documentation or in the implementation of their inherited member function FiniteElement::compare_for_domination(). Consider that a finite element may or may not dominate itself (e.g. FE_Nothing elements).
For example, if a FECollection consists of {FE_Q(1),FE_Q(2),FE_Q(3),FE_Q(4)}
elements and we are looking for the finite elements that dominate the middle elements of this collection (i.e., fes
is {1,2}
), then the answer is {FE_Q(1),FE_Q(2)
and therefore this function will return their indices in the FECollection, namely {0,1}
.
The codim
parameter describes the codimension of the investigated subspace and specifies that it is subject to this comparison. See FiniteElement::compare_for_domination() for more information.

.

unsigned int hp::FECollection< dim, spacedim >::find_dominating_fe  (  const std::set< unsigned int > &  fes,

Return the index of a finite element from the provided set of indices fes
that dominates all other elements of this very set.
You may find information about the domination behavior of finite elements in their respecitve class documentation or in the implementation of their inherited member function FiniteElement::compare_for_domination(). Consider that a finite element may or may not dominate itself (e.g. FE_Nothing elements).
If this set consists of exactly one element, we consider it to be the dominating one and return its corresponding index. Further, if the function is not able to find a finite element at all, it returns numbers::invalid_unsigned_int.
For example, if a FECollection consists of {FE_Q(1),FE_Q(2),FE_Q(3),FE_Q(4)}
elements and we are looking for the dominating finite element among the middle elements of this collection (i.e., fes
is {1,2}
), then the answer is FE_Q(2) and therefore this function will return its index in the FECollection, namely 1
.
It is of course possible that there is more than one element that dominates all selected elements. For example, if the collection consists of {FE_Q(1),FE_Q(1),FE_Q(2),FE_Q(2)}
and fes
covers all indices, then one could return zero or one. In that case, the function returns either 0
or 1
since there is no tiebreaker between the two.
