pyopensn.aquad.GLProductQuadrature1DSpherical

class pyopensn.aquad.GLProductQuadrature1DSpherical

Gauss-Legendre quadrature for 1D spherical geometry.

Wrapper of opensn::GLProductQuadrature1DSpherical.

The n_polar Gauss-Legendre directions are ordered by increasing direction cosine \(\mu\) and bracketed by zero-weight starting (\(\mu=-1\)) and final (\(\mu=+1\)) directions, which start and end the angular-derivative recursion. The weights sum to one. Use with pyopensn.solver.DiscreteOrdinatesCurvilinearProblem on a 1D mesh with coord_sys="spherical".
