reconstruct_fd_neighbor_work()

template<typename PrimTagsForReconstruction , typename PrimsTagsSentByNeighbor , typename TagsList , typename PrimsTags , size_t ThermodynamicDim, typename F0 , typename F1 >

void grmhd::ValenciaDivClean::fd::reconstruct_fd_neighbor_work	(	gsl::not_null< Variables< tags_list_for_reconstruct > * >	vars_on_face,
		const F0 &	reconstruct_lower_neighbor,
		const F1 &	reconstruct_upper_neighbor,
		const Variables< PrimsTags > &	subcell_volume_prims,
		const EquationsOfState::EquationOfState< true, ThermodynamicDim > &	eos,
		const Element< 3 > &	element,
		const DirectionalIdMap< 3, evolution::dg::subcell::GhostData > &	ghost_data,
		const Mesh< 3 > &	subcell_mesh,
		const Direction< 3 > &	direction_to_reconstruct,
		const size_t	ghost_zone_size,
		bool	compute_conservatives
	)

Reconstructs the PrimTagsForReconstruction and if compute_conservatives is true computes the Lorentz factor, upper spatial velocity, specific internal energy, and the conserved variables.

All results are written into vars_on_face.

This is used on DG elements to reconstruct their subcell neighbors' solution on the shared faces.

The reason the PrimTagsForReconstruction can be specified separately is because some variables might need separate reconstruction methods from others, e.g. to guarantee the reconstructed solution is positiv

reconstruct_prims_work()

template<typename PrimTagsForReconstruction , typename PrimsTagsVolume , size_t ThermodynamicDim, typename F , typename PrimsTagsSentByNeighbor >

void grmhd::ValenciaDivClean::fd::reconstruct_prims_work	(	gsl::not_null< std::array< Variables< tags_list_for_reconstruct >, 3 > * >	vars_on_lower_face,
		gsl::not_null< std::array< Variables< tags_list_for_reconstruct >, 3 > * >	vars_on_upper_face,
		const F &	reconstruct,
		const Variables< PrimsTagsVolume > &	volume_prims,
		const EquationsOfState::EquationOfState< true, ThermodynamicDim > &	eos,
		const Element< 3 > &	element,
		const DirectionalIdMap< 3, Variables< PrimsTagsSentByNeighbor > > &	neighbor_data,
		const Mesh< 3 > &	subcell_mesh,
		size_t	ghost_zone_size,
		bool	compute_conservatives
	)

Reconstructs the PrimTagsForReconstruction (usually $\rho ,p,W{v}^i,B^i$, and $\mathrm{\Phi }$), and if compute_conservatives is true computes the Lorentz factor, upper spatial velocity, specific internal energy, and the conserved variables.

All results are written into vars_on_lower_face and vars_on_upper_face.

The reason the PrimTagsForReconstruction can be specified separately is because some variables might need separate reconstruction methods from others, e.g. to guarantee the reconstructed solution is positive.
