Member Function Documentation

◆ AssembleCosines()

void chi_math::ProductQuadrature::AssembleCosines	(	const std::vector< double > &	azimuthal,
		const std::vector< double > &	polar,
		const std::vector< double > &	in_weights,
		bool	verbose
	)

Initializes the quadrature with custom angles and weights.

Definition at line 13 of file angular_product_quadrature.cc.

◆ GetAngleNum()

unsigned int chi_math::ProductQuadrature::GetAngleNum	(	const unsigned int	polar_angle_index,
		const unsigned int	azimu_angle_index
	)		const

inline

Obtains the abscissae index given the indices of the polar angle index and the azimuthal angle index.

Definition at line 55 of file angular_product_quadrature.h.

◆ GetDirectionMap()

const std::map< unsigned int, std::vector< unsigned int > > & chi_math::ProductQuadrature::GetDirectionMap ( ) const

inline

Return constant reference to map_directions.

Definition at line 60 of file angular_product_quadrature.h.

◆ OptimizeForPolarSymmetry()

void chi_math::ProductQuadrature::OptimizeForPolarSymmetry ( double normalization )

overridevirtual

Optimizes the angular quadrature for polar symmetry by removing all the direction with downward pointing polar angles.

Parameters

normalization float. (Optional) The default is a negative number which does not apply any normalization. If a positive number is provided, the weights will be normalized to sum to this number.

Reimplemented from chi_math::AngularQuadrature.
