| class | FEEvaluation |
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. The main usage is through the class FEEvaluation. However, there is functionality to construct an object of type FEEvaluationData given suitable data pointers to internal data, which allows usage in some scenarios where no full MatrixFree object is available.
This class has four template arguments:
| 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> |

| FEEvaluationData< dim, Number, is_face >::FEEvaluationData | ( | const ShapeInfoType & | shape_info, |
| const bool | is_interior_face = true |
||
| ) |
Constructor, taking a single ShapeInfo object to inject the capability for evaluation and set up some data containers, compatible with the internal evaluation kernels of FEEvaluationImpl and friends. For actual use, select one of the derived classes FEEvaluation or FEFaceEvaluation with their respective arguments.
|
default |
Copy constructor.
|
virtualdefault |
Destructor.
|
protected |
Constructor filling information available from a MatrixFree class, collected in an internal data structure to reduce overhead of initialization. Used in derived classes when this class is initialized from a MatrixFree object.
|
protected |
Constructor that comes with reduced functionality and works similarly as FEValues.
| FEEvaluationData & FEEvaluationData< dim, Number, is_face >::operator= | ( | const FEEvaluationData< dim, Number, is_face > & | other | ) |
Copy assignment operator.
| void FEEvaluationData< dim, Number, is_face >::set_data_pointers | ( | AlignedVector< Number > * | scratch_data, |
| const unsigned int | n_components | ||
| ) |
Sets the pointers for values, gradients, hessians to the central scratch_data_array inside the given scratch array, for a given number of components as provided by one of the derived classes.
| void FEEvaluationData< dim, Number, is_face >::reinit_face | ( | const internal::MatrixFreeFunctions::FaceToCellTopology< n_lanes > & | face | ) |
Initialize the indices related to the given face description. Used during the reinit() call of the FEFaceEvaluation class.
| ArrayView< Number > FEEvaluationData< dim, Number, is_face >::get_scratch_data | ( | ) | const |
Return an ArrayView to internal memory for temporary use. Note that some of this memory is overwritten during evaluate() and integrate() calls so do not assume it to be stable over those calls. The maximum size you can write into is 3*dofs_per_cell+2*n_q_points.
| Number FEEvaluationData< dim, Number, is_face >::JxW | ( | const unsigned int | q_point | ) | const |
Return the determinant of the Jacobian from the unit to the real cell times the quadrature weight.
| Point< dim, Number > FEEvaluationData< dim, Number, is_face >::quadrature_point | ( | const unsigned int | q | ) | const |
Returns the q-th quadrature point on the face in real coordinates stored in MappingInfo.
| Tensor< 2, dim, Number > FEEvaluationData< dim, Number, is_face >::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 \(J^{-\mathrm T} \hat{\nabla} u_h\).
| Tensor< 1, dim, Number > FEEvaluationData< dim, Number, is_face >::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.
is_face == true. | Tensor< 1, dim, Number > FEEvaluationData< dim, Number, is_face >::get_normal_vector | ( | const unsigned int | q_point | ) | const |
Same as normal_vector(const unsigned int q_point).
| const Number * FEEvaluationData< dim, Number, is_face >::begin_dof_values | ( | ) | const |
Return a read-only pointer to the first field of the dof values. This is the data field the read_dof_values() functions write into. First come the dof values for the first component, then all values for the second component, and so on. This is related to the internal data structures used in this class.

First come the function values on all quadrature points for the first component, then all values for the second component, and so on. This is related to the internal data structures used in this class.

In general, it is safer to use the get_value() function instead, which does all the transformation internally.
| Number * FEEvaluationData< dim, Number, is_face >::begin_values | ( | ) |

Return a read-only pointer to the first field of function gradients on quadrature points. First comes the x-component of the gradient for the first component on all quadrature points, then the y-component, and so on. Next comes the x-component of the second component, and so on. This is related to the internal data structures used in this class.

| const Number * FEEvaluationData< dim, Number, is_face >::begin_hessians | ( | ) | const |
Return a read-only pointer to the first field of function hessians on quadrature points. First comes the xx-component of the hessian for the first component on all quadrature points, then the yy-component, zz-component in (3d), then the xy-component, and so on. Next comes the xx-component of the second component, and so on. This is related to the internal data structures used in this class. The raw data after a call to evaluate only contains unit cell operations, so possible transformations, quadrature weights etc. must be applied manually. In general, it is safer to use the get_laplacian() or get_hessian() functions instead, which does all the transformation internally.
| Number * FEEvaluationData< dim, Number, is_face >::begin_hessians | ( | ) |

| unsigned int FEEvaluationData< dim, Number, is_face >::get_mapping_data_index_offset | ( | ) | const |
Return the index offset within the geometry fields for the cell the reinit() function has been called for.

Stores the subface index of the given face. Usually, this variable takes the value numbers::invalid_unsigned_int to indicate integration over the full face, but in case the current physical face has a neighbor that is more refined, it is a subface and must scale the entries in ShapeInfo appropriately.
