What is it about?
Ray effects through multidimensional isotropically scattering, participating media are investigated using discrete ordinates methods with four differents angular discretization.

Why is it important?
Ray effects are eliminated for combinations of higher-order azimuthal discretization and refined azimuthal discretization around the azimuthal angle endpoints.
Perspectives
Ray effects arise from the approximation of the continuously varying angular nature of the radiative intensity by a specified set of discrete angular directions. The propose angular discretization will be very useful to eleimated this fundamental shortcoming of the discrete ordinates/finite volume solution of the radiatve transfer equation if adopted in commercial software such as ANSYS Fluent
