class FEEvaluationAccess< dim, dofs_per_cell_, n_q_points_, 1, Number >
This class provides access to the data fields of the FEEvaluation classes. Partial specialization for scalar fields that defines access with simple data fields, i.e., scalars for the values and Tensor<1,dim> for the gradients.

template<int dim, int dofs_per_cell_, int n_q_points_, typename Number >
Returns the value stored for the local degree of freedom with index dof
. If the object is vector-valued, a vector-valued return argument is given. Note that when vectorization is enabled, values from several cells are grouped together. If set_dof_values
was called last, the value corresponds to the one set there. If integrate
was called last, it instead corresponds to the value of the integrated function with the test function of the given index.
template<int dim, int dofs_per_cell_, int n_q_points_, typename Number >
Returns the value of a finite element function at quadrature point number q_point
after a call to evaluate
(true,...), or the value that has been stored there with a call to submit_value
. If the object is vector-valued, a vector-valued return argument is given. Note that when vectorization is enabled, values from several cells are grouped together.
template<int dim, int dofs_per_cell_, int n_q_points_, typename Number >
Write a value to the field containing the values on quadrature points with component q_point
. Access to the same field as through get_value
. If applied before the function integrate
(true,...) is called, this specifies the value which is tested by all basis function on the current cell and integrated over.
template<int dim, int dofs_per_cell_, int n_q_points_, typename Number >
Returns the gradient of a finite element function at quadrature point number q_point
after a call to evaluate
(...,true,...), or the value that has been stored there with a call to submit_gradient
.
template<int dim, int dofs_per_cell_, int n_q_points_, typename Number >
Write a contribution that is tested by the gradient to the field containing the values on quadrature points with component q_point
. Access to the same field as through get_gradient
. If applied before the function integrate
(...,true) is called, this specifies what is tested by all basis function gradients on the current cell and integrated over.
template<int dim, int dofs_per_cell_, int n_q_points_, typename Number >
Returns the Hessian of a finite element function at quadrature point number q_point
after a call to evaluate
(...,true). If only the diagonal part of the Hessian or its trace, the Laplacian, are needed, use the respective functions below.
template<int dim, int dofs_per_cell_, int n_q_points_, typename Number >
Takes values on quadrature points, multiplies by the Jacobian determinant and quadrature weights (JxW) and sums the values for all quadrature points on the cell. The result is a scalar, representing the integral over the function over the cell. If a vector-element is used, the resulting components are still separated. Moreover, if vectorization is enabled, the integral values of several cells are represented together.
