class	FEEvaluation

Detailed Description

template<int dim, typename Number, bool is_face, typename VectorizedArrayType>
class FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >

This base class of the FEEvaluation and FEFaceEvaluation classes handles mapping-related information independent of the degrees of freedom and finite element in use. This class provides access functionality for user code but is otherwise invisible without any public constructor. The usage is through the class FEEvaluation instead.

This class has four template arguments:

Template Parameters

dim	Dimension in which this class is to be used
Number	Number format, usually `double` or `float`
is_face	Whether the class is used for a cell integrator (with quadrature dimension the same as the space dimension) or for a face integrator (with quadrature dimension one less)
VectorizedArrayType	Type of array to be woked on in a vectorized fashion, defaults to VectorizedArray<Number>

Note: Currently only VectorizedArray<Number, width> is supported as VectorizedArrayType.

Constructor & Destructor Documentation

◆ ~FEEvaluationBaseData()

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::~FEEvaluationBaseData ( )

Destructor.

◆ FEEvaluationBaseData() [1/3]

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::FEEvaluationBaseData	(	const MatrixFree< dim, Number, VectorizedArrayType > &	matrix_free,
		const unsigned int	dof_no,
		const unsigned int	first_selected_component,
		const unsigned int	quad_no,
		const unsigned int	fe_degree,
		const unsigned int	n_q_points,
		const bool	is_interior_face,
		const unsigned int	active_fe_index,
		const unsigned int	active_quad_index,
		const unsigned int	face_type
	)

protected

Constructor. Made protected to prevent users from directly using this class. Takes all data stored in MatrixFree. If applied to problems with more than one quadrature formula selected during construction of matrix_free, quad_no allows to select the appropriate formula.

◆ FEEvaluationBaseData() [2/3]

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::FEEvaluationBaseData	(	const Mapping< dim > &	mapping,
		const FiniteElement< dim > &	fe,
		const Quadrature< 1 > &	quadrature,
		const UpdateFlags	update_flags,
		const unsigned int	first_selected_component,
		const FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType > *	other
	)

protected

Constructor that comes with reduced functionality and works similar as FEValues.

◆ FEEvaluationBaseData() [3/3]

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::FEEvaluationBaseData ( const FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType > & other )

protected

Copy constructor. If FEEvaluationBase was constructed from a mapping, fe, quadrature, and update flags, the underlying geometry evaluation based on FEValues will be deep-copied in order to allow for using in parallel with threads.

Member Function Documentation

◆ get_mapping_data_index_offset()

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

unsigned int FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::get_mapping_data_index_offset ( ) const

Return the index offset within the geometry fields for the cell the reinit() function has been called for. This index can be used to access an index into a field that has the same compression behavior as the Jacobian of the geometry, e.g., to store an effective coefficient tensors that combines a coefficient with the geometry for lower memory transfer as the available data fields.

◆ get_cell_type()

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

internal::MatrixFreeFunctions::GeometryType FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::get_cell_type ( ) const

Return the type of the cell the reinit() function has been called for. Valid values are cartesian for Cartesian cells (which allows for considerable data compression), affine for cells with affine mappings, and general for general cells without any compressed storage applied.

◆ get_shape_info()

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

const internal::MatrixFreeFunctions::ShapeInfo< VectorizedArrayType > & FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::get_shape_info ( ) const

Return a reference to the ShapeInfo object currently in use.

◆ get_dof_info()

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

const internal::MatrixFreeFunctions::DoFInfo & FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::get_dof_info ( ) const

Return a reference to the DoFInfo object currently in use.

◆ JxW()

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

VectorizedArrayType FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::JxW ( const unsigned int q_point ) const

Return the determinant of the Jacobian from the unit to the real cell times the quadrature weight.

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

Tensor< 2, dim, VectorizedArrayType > FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::inverse_jacobian ( const unsigned int q_point ) const

Return the inverse and transposed version \(J^{-\mathrm T}\) of the Jacobian of the mapping between the unit to the real cell defined as \(J_{ij} = d x_i / d\hat x_j\). The \((i,j)\) entry of the returned tensor contains \(d\hat x_j/dx_i\), i.e., columns refer to reference space coordinates and rows to real cell coordinates. Thus, the returned tensor represents a covariant transformation, which is used in the FEEvaluationBase::get_gradient() function to transform the unit cell gradients to gradients on the real cell by a multiplication \(J^{-\mathrm T} \hat{\nabla} u_h\).

◆ get_normal_vector()

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

Tensor< 1, dim, VectorizedArrayType > FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::get_normal_vector ( const unsigned int q_point ) const

Return the unit normal vector on a face. Note that both sides of a face use the same orientation of the normal vector: For the faces enumerated as interior in FaceToCellTopology and selected with the is_interior_face=true flag of the constructor, this corresponds to the outer normal vector, whereas for faces enumerated as exterior in FaceToCellTopology and selected with the is_interior_face=false flag of the constructor, the normal points into the element as a consequence of the single normal vector.

Note: Only implemented in case is_face == true.

◆ read_cell_data() [1/2]

template<int dim, typename Number , bool is_face, typename VectorizedArrayType >

VectorizedArrayType FEEvaluationBaseData< dim, Number, is_face, VectorizedArrayType >::read_cell_data ( const AlignedVector< VectorizedArrayType > & array ) const

	)		const

Provides a unified interface to set data in a vector of VectorizedArray fields of length MatrixFree::n_cell_batches() + MatrixFree::n_ghost_cell_batches() for both cells (plain read) and faces (indirect addressing).
