Detailed Description

template<int dim, int n_components_, typename Number, bool is_face>
class FEEvaluationAccess< dim, n_components_, Number, is_face >

This class provides access to the data fields of the FEEvaluation classes. Generic access is achieved through the base class, and specializations for scalar and vector-valued elements are defined separately.

Constructor & Destructor Documentation

◆ FEEvaluationAccess() [1/3]

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

FEEvaluationAccess< dim, n_components_, Number, is_face >::FEEvaluationAccess	(	const MatrixFree< dim, Number > &	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 = `true`
	)

protected

Constructor. Made protected to prevent initialization in user code. Takes all data stored in MatrixFree. If applied to problems with more than one finite element or more than one quadrature formula selected during construction of matrix_free, first_selected_component and quad_no allow to select the appropriate components.

◆ FEEvaluationAccess() [2/3]

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

template<int n_components_other>

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

protected

Constructor with reduced functionality for similar usage of FEEvaluation as FEValues, including matrix assembly.
