Finite element evaluated in quadrature points on a face.
This class adds the functionality of FEFaceValuesBase to FEValues; see there for more documentation.
This class is used for faces lying on a refinement edge. In this case, the neighboring cell is refined. To be able to compute differences between interior and exterior function values, the refinement of the neighboring cell must be simulated on this cell. This is achieved by applying a quadrature rule that simulates the refinement. The resulting data fields are split up to reflect the refinement structure of the neighbor: a subface number corresponds to the number of the child of the neighboring face.

| const Quadrature< dim - 1 > & | face_quadrature, | ||

Constructor. Gets cell independent data from mapping and finite element objects, matching the quadrature rule and update flags.

| const UpdateFlags | update_flags | ||
| ) |
Constructor. This constructor is equivalent to the other one except that it makes the object use a \(Q_1\) mapping (i.e., an object of type MappingQGeneric(1)) implicitly.

| const unsigned int | face_no, | ||
| const unsigned int | subface_no | ||
| ) |
Reinitialize the gradients, Jacobi determinants, etc for the given cell of type "iterator into a DoFHandler object", and the finite element associated with this object. It is assumed that the finite element used by the given cell is also the one used by this FESubfaceValues object.
Definition at line 4940 of file fe_values.cc.
| void FESubfaceValues< dim, spacedim >::reinit | ( | const typename Triangulation< dim, spacedim >::cell_iterator & | cell, |
| const unsigned int | face_no, | ||
| const unsigned int | subface_no | ||
| ) |
Reinitialize the gradients, Jacobi determinants, etc for the given subface on given cell of type "iterator into a Triangulation object", and the given finite element. Since iterators into triangulation alone only convey information about the geometry of a cell, but not about degrees of freedom possibly associated with this cell, you will not be able to call some functions of this class if they need information about degrees of freedom. These functions are, above all, the get_function_value/gradients/hessians/third_derivatives functions. If you want to call these functions, you have to call the reinit variants that take iterators into DoFHandler or other DoF handler type objects.
Definition at line 4988 of file fe_values.cc.
| const FESubfaceValues<dim, spacedim>& FESubfaceValues< dim, spacedim >::get_present_fe_values | ( | ) | const |
Return a reference to this very object.
Though it seems that it is not very useful, this function is there to provide capability to the hp::FEValues class, in which case it provides the FEValues object for the present cell (remember that for hp finite elements, the actual FE object used may change from cell to cell, so we also need different FEValues objects for different cells; once you reinitialize the hp::FEValues object for a specific cell, it retrieves the FEValues object for the FE on that cell and returns it through a function of the same name as this one; this function here therefore only provides the same interface so that one can templatize on FEValues and hp::FEValues).

Do work common to the two constructors.

The reinit() functions do only that part of the work that requires knowledge of the type of iterator. After setting present_cell(), they pass on to this function, which does the real work, and which is independent of the actual type of the cell iterator.
