Detailed Description

template<int spacedim>
class FE_FaceQ< 1, spacedim >

Specialization of FE_FaceQ for 1D. In that case, the finite element only consists of one degree of freedom in each of the two faces (= vertices) of a cell, irrespective of the degree. However, this element still accepts a degree in its constructor and also returns that degree. This way, dimension-independent programming with trace elements is also possible in 1D (even though there is no computational benefit at all from it in 1D).

◆ get_name()

template<int spacedim>
std::string FE_FaceQ< 1, spacedim >::get_name
overridevirtual

Return a string that uniquely identifies a finite element. This class returns FE_FaceQ<dim>(degree), with dim and degree replaced by appropriate values.

◆ requires_update_flags()

template<int spacedim>
UpdateFlags FE_FaceQ< 1, spacedim >::requires_update_flags ( const UpdateFlags  update_flags) const
overridevirtual

Given a set of update flags, compute which other quantities also need to be computed in order to satisfy the request by the given flags. Then return the combination of the original set of flags and those just computed.

As an example, if update_flags contains update_gradients a finite element class will typically require the computation of the inverse of the Jacobian matrix in order to rotate the gradient of shape functions on the reference cell to the real cell. It would then return not just update_gradients, but also update_covariant_transformation, the flag that makes the mapping class produce the inverse of the Jacobian matrix.

An extensive discussion of the interaction between this function and FEValues can be found in the How Mapping, FiniteElement, and FEValues work together documentation module.

template<int spacedim>
void FE_FaceQ< 1, spacedim >::get_face_interpolation_matrix ( const FiniteElement< 1, spacedim > &  source,
FullMatrix< double > &  matrix 
) const
overridevirtual

Return the matrix interpolating from a face of one element to the face of the neighboring element. The size of the matrix is then source.dofs_per_face times this->dofs_per_face. This element only provides interpolation matrices for elements of the same type and FE_Nothing. For all other elements, an exception of type FiniteElement<dim,spacedim>::ExcInterpolationNotImplemented is thrown.

void FE_FaceQ< 1, spacedim >::get_subface_interpolation_matrix ( const FiniteElement< 1, spacedim > &  source,
const unsigned int  subface,
FullMatrix< double > &  matrix 
) const
overridevirtual

Return the matrix interpolating from a face of one element to the face of the neighboring element. The size of the matrix is then source.dofs_per_face times this->dofs_per_face. This element only provides interpolation matrices for elements of the same type and FE_Nothing. For all other elements, an exception of type FiniteElement<dim,spacedim>::ExcInterpolationNotImplemented is thrown.

template<int spacedim>
bool FE_FaceQ< 1, spacedim >::has_support_on_face ( const unsigned int  shape_index,
const unsigned int  face_index

overridevirtual

This function returns true, if the shape function shape_index has non-zero function values somewhere on the face face_index.

Reimplemented from FiniteElement< 1, spacedim >.

◆ hp_constraints_are_implemented()

template<int spacedim>
bool FE_FaceQ< 1, spacedim >::hp_constraints_are_implemented
overridevirtual

Return whether this element implements its hanging node constraints in the new way, which has to be used to make elements "hp compatible".

Definition at line 606 of file fe_face.cc.

◆ hp_vertex_dof_identities()

template<int spacedim>
std::vector< std::pair< unsigned int, unsigned int > > FE_FaceQ< 1, spacedim >::hp_vertex_dof_identities ( const FiniteElement< 1, spacedim > &  fe_other) const
overridevirtual

If, on a vertex, several finite elements are active, the hp code first assigns the degrees of freedom of each of these FEs different global indices. It then calls this function to find out which of them should get identical values, and consequently can receive the same global DoF index. This function therefore returns a list of identities between DoFs of the present finite element object with the DoFs of fe_other, which is a reference to a finite element object representing one of the other finite elements active on this particular vertex. The function computes which of the degrees of freedom of the two finite element objects are equivalent, both numbered between zero and the corresponding value of dofs_per_vertex of the two finite elements. The first index of each pair denotes one of the vertex dofs of the present element, whereas the second is the corresponding index of the other finite element.

The set of such constraints is non-empty only for dim==1.

Definition at line 613 of file fe_face.cc.

◆ hp_line_dof_identities()

template<int spacedim>
std::vector< std::pair< unsigned int, unsigned int > > FE_FaceQ< 1, spacedim >::hp_line_dof_identities ( const FiniteElement< 1, spacedim > &  fe_other) const
overridevirtual

Same as hp_vertex_dof_indices(), except that the function treats degrees of freedom on lines.

The set of such constraints is non-empty only for dim==2.

Definition at line 626 of file fe_face.cc.

◆ hp_quad_dof_identities()

template<int spacedim>
std::vector< std::pair< unsigned int, unsigned int > > FE_FaceQ< 1, spacedim >::hp_quad_dof_identities ( const FiniteElement< 1, spacedim > &  fe_other) const
overridevirtual

Same as hp_vertex_dof_indices(), except that the function treats degrees of freedom on quads.

The set of such constraints is non-empty only for dim==3.

◆ get_constant_modes()

template<int spacedim>
std::pair< Table< 2, bool >, std::vector< unsigned int > > FE_FaceQ< 1, spacedim >::get_constant_modes
