pyopensn.aquad.TriangularQuadrature

class pyopensn.aquad.TriangularQuadrature

Triangular quadrature base class.

Unlike product quadratures which have a fixed number of azimuthal angles per polar level, triangular quadratures have a varying number of azimuthal angles that decreases as the polar angle moves away from the equatorial plane.
