Diffusion-Accelerated Solution of the Two-Dimensional Sn Equations with Bilinear-Discontinuous Differencing Academic Article uri icon


  • A new diffusion synthetic acceleration scheme is developed for solving the two-dimensional Snequations in x-y geometry with bilinear-discontinuous finite element spatial discretization. This method differs from previous methods in that it is unconditionally efficient for problems with isotropic or weakly anisotropic scattering. Computational results are given that demonstrate this property.
