| Summary: | Analysis for a continuous set of equations and report TSA behavior. We show that a previously proposed TSA method is Characteristics and two Bilinear Discontinuous methods, and development and the realization of the method for an especially well. We further demonstrate that TSA achieves a features represent simple and efficient improvements to the find that discretization enhances TSA performance. We then for descritized transport equations, using Step- function of the scattering ratio. We devote the final isotropic source in XY geometry. We carry out a Fourier Iteration, regardless of discretization parameters or itself a simplified transport problem. We describe the materials and emphasize that this gain is an increasing method. We test TSA on a series of physical problems and methods to iteratively solve within-group scattering order problem, to use a crude quadrature set in the low-order problem and to set the number of low-order iterations per problems. A single iteration in these schemes consists of a propose a set of parameters for which the method behaves propose to implement a Conjugate Gradient method on the low- section to some conclusions and suggestions for future work. stable and rapidly convergent. We follow the same procedure substantial reduction in computational cost over Source transport sweep followed by a low-order calculation which is transport sweep to a finite value. We prove that these unstable in two dimensions but that our modifications make it We present a family of Transport Synthetic Acceleration (TSA) |
