template<int , int dim, typename NumberType > | |
using | type = SymmetricTensor< 2, dim, NumberType > |
An intermediate helper struct that defines the return type of Hessian (second derivative) calculations of scalar fields with respect to fields defined by the two extractor-type template parameters. This particular specialization is for taking the first derivative with respect to a scalar field, and the second with respect to a symmetric tensor field.

using Differentiation::AD::internal::HessianType< FEValuesExtractors::Scalar, FEValuesExtractors::SymmetricTensor< 2 > >::type = SymmetricTensor<2 , dim, NumberType> |

followed by the ExtractorType_Col = FEValuesExtractors::SymmetricTensor<2>
.
