reconstruct_fd_neighbor_work()

template<size_t Dim, typename TagsList, typename ReconstructLower, typename ReconstructUpper>

void ScalarAdvection::fd::reconstruct_fd_neighbor_work	(	gsl::not_null< Variables< TagsList > * >	vars_on_face,
		const ReconstructLower &	reconstruct_lower_neighbor,
		const ReconstructUpper &	reconstruct_upper_neighbor,
		const Variables< tmpl::list< Tags::U > > &	subcell_volume_vars,
		const Element< Dim > &	element,
		const DirectionalIdMap< Dim, evolution::dg::subcell::GhostData > &	ghost_data,
		const Mesh< Dim > &	subcell_mesh,
		const Direction< Dim > &	direction_to_reconstruct,
		const size_t	ghost_zone_size )

Reconstructs the scalar field \(U\) for a given direction. All results are written into vars_on_face.

This is used on DG elements to reconstruct \(U\) with their subcell neighbors' solution (ghost data received) on the shared faces.
