Detailed Description

template<int dim, int spacedim = dim>
class FEFaceValues< dim, spacedim >

Finite element evaluated in quadrature points on a face.

This class adds the functionality of FEFaceValuesBase to FEValues; see there for more documentation.

Since finite element functions and their derivatives may be discontinuous at cell boundaries, there is no restriction of this function to a mesh face. But, there are limits of these values approaching the face from either of the neighboring cells.

Constructor & Destructor Documentation

template<int dim, int spacedim>

FEFaceValues< dim, spacedim >::FEFaceValues	(	const Mapping< dim, spacedim > &	mapping,
		const FiniteElement< dim, spacedim > &	fe,
		const Quadrature< dim-1 > &	quadrature,
		const UpdateFlags	update_flags
	)

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

Definition at line 4762 of file fe_values.cc.

template<int dim, int spacedim>

FEFaceValues< dim, spacedim >::FEFaceValues	(	const FiniteElement< dim, spacedim > &	fe,
		const Quadrature< dim-1 > &	quadrature,
		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.

template<template< int, int > class DoFHandlerType, bool lda>

void FEFaceValues< dim, spacedim >::reinit	(	const TriaIterator< DoFCellAccessor< DoFHandlerType< dim, spacedim >, lda >> &	cell,
		const unsigned int	face_no
	)

Reinitialize the gradients, Jacobi determinants, etc for the face with number face_no of cell and the given finite element.

Definition at line 4845 of file fe_values.cc.

template<int dim, int spacedim>

void FEFaceValues< dim, spacedim >::reinit	(	const typename Triangulation< dim, spacedim >::cell_iterator &	cell,
		const unsigned int	face_no
	)

Reinitialize the gradients, Jacobi determinants, etc for the given face 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 4875 of file fe_values.cc.

template<int dim, int spacedim = dim>

const FEFaceValues<dim, spacedim>& FEFaceValues< 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).

template<int dim, int spacedim>

void FEFaceValues< dim, spacedim >::initialize ( const UpdateFlags update_flags )

private

Do work common to the two constructors.

Definition at line 4798 of file fe_values.cc.

template<int dim, int spacedim>

void FEFaceValues< dim, spacedim >::do_reinit ( const unsigned int face_no )

private

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.
