◆ approximate_cell()

template<class DerivativeDescription, int dim, class InputVector, int spacedim>

void DerivativeApproximation::internal::approximate_cell	(	const Mapping< dim, spacedim > &	mapping,
		const DoFHandler< dim, spacedim > &	dof_handler,
		const InputVector &	solution,
		const unsigned int	component,
		const typename DoFHandler< dim, spacedim >::active_cell_iterator &	cell,
		typename DerivativeDescription::Derivative &	derivative )

Compute the derivative approximation on one cell. This computes the full derivative tensor.

◆ approximate()

template<class DerivativeDescription, int dim, class InputVector, int spacedim>

void DerivativeApproximation::internal::approximate	(	const SynchronousIterators< std::tuple< typename DoFHandler< dim, spacedim >::active_cell_iterator, Vector< float >::iterator > > &	cell,
		const Mapping< dim, spacedim > &	mapping,
		const DoFHandler< dim, spacedim > &	dof_handler,
		const InputVector &	solution,
		const unsigned int	component )

Compute the derivative approximation on a given cell. Fill the derivative_norm vector with the norm of the computed derivative tensors on the cell.

◆ approximate_derivative()

template<class DerivativeDescription, int dim, class InputVector, int spacedim>

void DerivativeApproximation::internal::approximate_derivative	(	const Mapping< dim, spacedim > &	mapping,
		const DoFHandler< dim, spacedim > &	dof_handler,
		const InputVector &	solution,
		const unsigned int	component,
		Vector< float > &	derivative_norm )

Kind of the main function of this class. It is called by the public entry points to this class with the correct template first argument and then simply calls the approximate function, after setting up several threads and doing some administration that is independent of the actual derivative to be computed.

The component argument denotes which component of the solution vector we are to work on.
