A helper struct that assists with the extraction of data associated with fields that are defined by FEExtractors. This particular specialization is for scalar fields.

using Differentiation::AD::internal::Extractor< dim, FEValuesExtractors::Scalar >::tensor_type = Tensor<rank, dim, NumberType> |
The tensor type associated with this field.
Definition at line 1673 of file ad_helpers.h.
using Differentiation::AD::internal::Extractor< dim, FEValuesExtractors::Scalar >::value_type = NumberType |
The value type associated with this field.
Definition at line 1690 of file ad_helpers.h.
using Differentiation::AD::internal::Extractor< dim, FEValuesExtractors::Scalar >::gradient_type = Tensor<rank + 1, dim, NumberType> |
The gradient type associated with this field.

|
inlinestatic |
Return the first global component of this field.
Definition at line 1702 of file ad_helpers.h.
|
inlinestatic |
Return a flag that indicates if the input unrolled_index
corresponds to a symmetric component of the field.
For a scalar field, the single component is defined to not have a symmetric counterpart.
Definition at line 1715 of file ad_helpers.h.
|
inlinestatic |
Return the local unrolled component corresponding to column_offset
entry of the table_indices
.
For a scalar field, the local component is always equal to zero.
Definition at line 1730 of file ad_helpers.h.
|
static |
The number of components of the field.
Definition at line 1662 of file ad_helpers.h.
|
static |
The tensor rank of the field.
