Function Documentation

◆ factorial()

int MoltresUtils::factorial ( int n )

◆ level_symmetric()

RealEigenMatrix MoltresUtils::level_symmetric ( unsigned int N )

Returns a (N*(N+2))-by-4 RealEigenMatrix with each row consisting of the three components of the Cartesian direction vector and its associated level-symmetric weight.

◆ permute_octant()

RealEigenMatrix MoltresUtils::permute_octant	(	RealEigenMatrix	m,
		unsigned int	idx,
		Real	mu1,
		Real	mu2,
		Real	mu3,
		Real	w )

Returns all possible signed permutations of mu1,mu2,mu3.

◆ points()

std::vector< Real > MoltresUtils::points ( unsigned int N )

Returns possible Cartesian direction vector components under the level-symmetric quadrature for a given order N.

◆ sph_harmonics()

Real MoltresUtils::sph_harmonics	(	int	l,
		int	m,
		Real	mu,
		Real	eta,
		Real	xi )

Returns the output of the real spherical harmonic function of degree l and order m, given an input Cartesian direction vector (mu, eta, xi).

◆ sph_harmonics_mat()

RealEigenMatrix MoltresUtils::sph_harmonics_mat	(	int	L,
		RealEigenMatrix	ordinates )

Returns the output of sph_harmonics for all combinations of l and m for an array of Cartesian direction vectors as a matrix.

◆ weights()

std::vector< Real > MoltresUtils::weights ( unsigned int N )

Returns possible weight values under the level-symmetric quadrature for a given order N.

◆ x_reflection_map()

unsigned int MoltresUtils::x_reflection_map ( unsigned int i )

Cartesian reflected flux ID maps. Refer to permute_octant for the permutation order of all flux variables with the same direction vector components.

◆ y_reflection_map()

unsigned int MoltresUtils::y_reflection_map ( unsigned int i )

◆ z_reflection_map()

unsigned int MoltresUtils::z_reflection_map ( unsigned int i )
