title = "A diffusion synthetic acceleration scheme for rectangular geometries based on bilinear discontinuous finite elements",
abstract = "A DSA technique to accelerate the iterative convergence of Sn transport solves is derived for bilinear discontinuous (BLD) finite elements on rectangular grids. The diffusion synthetic acceleration equations are discretized using BLD elements by adapting the Modified Interior Penalty technique, introduced in [4] for triangular grids. The MIP-DSA equations are SPD and thus are solved using a preconditioned CG technique. Fourier analyses and implementation of the technique in a BLD 5n transport code show that the technique is stable is effective.",
