“…In this section we extend the mathematical analysis of the error bound estimate and convergence to the mono-energetic nodal-LT S N solution in a rectangle proposed in [HaEtAl08]. We discuss the conditions for the convergence of the discrete ordinates nodal method, LT S N , mentioned in [Ze90], [KaLeHe82], [Kh97], [PaVi99], [KhSb05a], [KhSb05b], [HaEtAl08].…”
