Namespaces
namespace	oomph
	DRAIG: Change all instances of (SPATIAL_DIM) to (DIM-1).
namespace	oomph::HypreHelpers
	Helper functions for use with the Hypre library.
namespace	oomph::Hypre_default_settings
	Default settings for various uses of the HYPRE solver.

Functions
int	oomph::HypreHelpers::check_HYPRE_error_flag (std::ostringstream &message)
	Helper function to check the Hypre error flag, return the message associated with any error, and reset the global error flag to zero. This function also returns the error value.
void	oomph::HypreHelpers::create_HYPRE_Vector (const DoubleVector &oomph_vec, const LinearAlgebraDistribution *dist_pt, HYPRE_IJVector &hypre_ij_vector, HYPRE_ParVector &hypre_par_vector)
	Helper function to create a HYPRE_IJVector and HYPRE_ParVector.
void	oomph::HypreHelpers::create_HYPRE_Vector (const LinearAlgebraDistribution *dist_pt, HYPRE_IJVector &hypre_ij_vector, HYPRE_ParVector &hypre_par_vector)
	Helper function to create a HYPRE_IJVector and HYPRE_ParVector.
void	oomph::HypreHelpers::create_HYPRE_Matrix (CRDoubleMatrix *oomph_matrix, HYPRE_IJMatrix &hypre_ij_matrix, HYPRE_ParCSRMatrix &hypre_par_matrix, LinearAlgebraDistribution *dist_pt)
	Helper function to create a serial HYPRE_IJMatrix and HYPRE_ParCSRMatrix from a CRDoubleMatrix NOTE: dist_pt is rebuilt to match the distribution of the hypre solver which is not necassarily the same as the oomph lib matrix.
void	oomph::HypreHelpers::euclid_settings_helper (const bool &use_block_jacobi, const bool &use_row_scaling, const bool &use_ilut, const int &level, const double &drop_tol, const int &print_level, HYPRE_Solver &euclid_object)
	Helper function to set Euclid options using a command line like array.
void	oomph::Hypre_default_settings::set_defaults_for_navier_stokes_momentum_block (HyprePreconditioner *hypre_preconditioner_pt)
	Set default parameters for use as preconditioner in for momentum block in Navier-Stokes problem.
void	oomph::Hypre_default_settings::set_defaults_for_2D_poisson_problem (HyprePreconditioner *hypre_preconditioner_pt)
	Set default parameters for use as preconditioner in 2D Poisson-type problem.
void	oomph::Hypre_default_settings::set_defaults_for_3D_poisson_problem (HyprePreconditioner *hypre_preconditioner_pt)
	Set default parameters for use as preconditioner in 3D Poisson-type problem.
