		const unsigned int	interface_dof_index,
		const unsigned int	q_point
	)		const

Return the value of the vector components selected by this view with interface dof index interface_dof_index in quadrature point q_point.

The argument here_or_there selects between the upstream value and the downstream value as defined by the direction of the normal vector in this quadrature point. If here_or_there is true, the shape functions from the first cell of the interface is used.

In other words, this function returns the limit of the value of the shape function in the given quadrature point when approaching it from one of the two cells of the interface.

Note: This function is typically used to pick the upstream or downstream value based on a direction. This can be achieved by using (direction * normal)>0 as the first argument of this function.

◆ get_function_values()

template<int dim, int spacedim = dim>

template<class InputVector >

void FEInterfaceViews::Vector< dim, spacedim >::get_function_values	(	const bool	here_or_there,
		const InputVector< dim, spacedim > &	fe_function,
		std::vector< solution_value_type< typename InputVector< dim, spacedim >::value_type > > &	values
	)		const

Return the values of the selected vector component of the finite element function characterized by fe_function at the quadrature points of the cell interface selected the last time the reinit function of the FEInterfaceValues object was called.

The argument here_or_there selects between the value on cell 0 (here, true) and cell 1 (there, false). You can also interpret it as "upstream" (true) and "downstream" (false) as defined by the direction of the normal vector in this quadrature point. If here_or_there is true, the values from the first cell of the interface is used.

The data type stored by the output vector must be what you get when you multiply the values of shape functions (i.e., value_type) times the type used to store the values of the unknowns \(U_j\) of your finite element vector \(U\) (represented by the fe_function argument).

Note: For this function to work properly, the underlying FEValues, FEFaceValues, or FESubfaceValues object on which you call it must have computed the information you are requesting. To do so, the update_values flag must be an element of the list of UpdateFlags that you passed to the constructor of this object. See The interplay of UpdateFlags, Mapping, and FiniteElement in FEValues for more information.

◆ get_function_values_from_local_dof_values()

		const InputVector< dim, spacedim > &	local_dof_values,
		std::vector< solution_value_type< typename InputVector< dim, spacedim >::value_type > > &	values
	)		const

Same as above, but using a vector of local degree-of-freedom values. In other words, instead of extracting the nodal values of the degrees of freedom located on the current cell interface from a global vector associated with a DoFHandler object (as the function above does), this function instead takes these local nodal values through its first argument.

Parameters

[in]	here_or_there	Same as the one in the above function.
[in]	local_dof_values	A vector of local nodal values. This vector must have a length equal to number of DoFs on the current cell, and must be ordered in the same order as degrees of freedom are numbered on the reference cell.
[out]	values	A vector of values of the given finite element field, at the quadrature points on the current object.

Template Parameters

InputVector The InputVector type must allow creation of an ArrayView object from it; this is satisfied by the std::vector class, among others.

The data type stored by the output vector must be what you get when you multiply the values of shape functions (i.e., value_type) times the type used to store the values of the unknowns \(U_j\) of your finite element vector \(U\) (represented by the fe_function argument).

Note: For this function to work properly, the underlying FEValues, FEFaceValues, or FESubfaceValues object on which you call it must have computed the information you are requesting. To do so, the update_values flag must be an element of the list of UpdateFlags that you passed to the constructor of this object. See The interplay of UpdateFlags, Mapping, and FiniteElement in FEValues for more information.

	)		const

This function relates to get_average_of_function_values() in the same way as get_function_values_from_local_dof_values() relates to get_function_values(). See the documentation of get_function_values_from_local_dof_values() for more information.

◆ get_average_of_function_gradients()

		std::vector< solution_gradient_type< typename InputVector< dim, spacedim >::value_type > > &	gradients
	)		const

Return the average of the gradients of the selected vector components of the finite element function characterized by fe_function at the quadrature points of the cell interface selected the last time the reinit function of the FEInterfaceValues object was called.

The data type stored by the output vector must be what you get when you multiply the gradients of shape functions (i.e., gradient_type) times the type used to store the values of the unknowns \(U_j\) of your finite element vector \(U\) (represented by the fe_function argument).

Note: For this function to work properly, the underlying FEValues, FEFaceValues, or FESubfaceValues object on which you call it must have computed the information you are requesting.

	)		const

This function relates to get_average_of_function_gradients() in the same way as get_function_values_from_local_dof_values() relates to get_function_values(). See the documentation of get_function_values_from_local_dof_values() for more information.

		std::vector< solution_hessian_type< typename InputVector< dim, spacedim >::value_type > > &	hessians
	)		const

Return the average of the Hessians of the selected vector component of the finite element function characterized by fe_function at the quadrature points of the cell, face or subface selected the last time the reinit function of the FEInterfaceValues object was called.

The data type stored by the output vector must be what you get when you multiply the Hessians of shape functions (i.e., hessian_type) times the type used to store the values of the unknowns \(U_j\) of your finite element vector \(U\) (represented by the fe_function argument).

Note: For this function to work properly, the underlying FEValues, FEFaceValues, or FESubfaceValues object on which you call it must have computed the information you are requesting.
