Abstract:
Discrete-ordinate radiation transport simulations suffer from so-called ray effects. These are artefacts in the solution which come from the discretization into finitely many directions of flight. We present and analyze a method that successively rotates the angular grid and interpolates the solution onto it. The method is simple to implement, and we show promising preliminary numerical results.
