Classes
struct	serac::DependsOn< i >
struct	serac::Index< ind >
	Compile-time alias for index of differentiation. More...
class	serac::Functional< test(trials...), exec >
	Intended to be like std::function for finite element kernels. More...

Namespaces
	serac
	Accelerator functionality.

Functions
template<typename... T>
constexpr uint32_t	serac::index_of_differentiation ()
	given a list of types, this function returns the index that corresponds to the type dual_vector. More...
void	serac::check_for_missing_nodal_gridfunc (const mfem::Mesh &mesh)
	function for verifying that the mesh has been fully initialized
void	serac::check_for_unsupported_elements (const mfem::Mesh &mesh)
	function for verifying that there are no unsupported element types in the mesh
template<typename function_space >
std::pair< std::unique_ptr< mfem::ParFiniteElementSpace >, std::unique_ptr< mfem::FiniteElementCollection > >	serac::generateParFiniteElementSpace (mfem::ParMesh *mesh)
	create an mfem::ParFiniteElementSpace from one of serac's tag types: H1, Hcurl, L2 More...
void	serac::updateFaceNbrData (const mfem::ParFiniteElementSpace *const_trial_space, mfem::ParGridFunction &trial_pgf, mfem::Vector &trial_tdof_vals)
	helper function to locally cast away const on FE space so we can update face neighbor data with ExchangeFaceNbrData. This is ok because : 1) the original trial FE space is declared without const; 2) we constrained the non-constness locally; 3) the locally owned data associated with the trial function space is NOT altered and ONLY ghost data is updated.
void	serac::appendFaceNbrData (const mfem::ParFiniteElementSpace *trial_space, const mfem::ParGridFunction &trial_pgf, const int LSize, mfem::Vector &input_L)
	helper functional to reorder the ordering of FaceNbrData for L2 space to byVDIM and append this vector to the end of local dof vector, which will result in a vector in form [ — L — | — FND — ]
void	serac::rearrangeFaceNbrDofGlobalIndex (const mfem::ParFiniteElementSpace *trial_space, mfem::Array< HYPRE_BigInt > &face_nbr_glob_vdof_map)
	helper functional to reorder the face_nbr_glob_dof_map for L2 space to byVDIM
