Nonlinear Acceleration of a Continuous Finite Element Discretization of the Self-Adjoint Angular Flux Form of the Transport Equation

Journal Article Sanchez, Richard ; Rabiti, Cristian ; Wang, Yaqi - Nuclear Science and Engineering

Nonlinear acceleration of a continuous finite element (CFE) discretization of the transport equation requires a modification of the transport solution in order to achieve local conservation, a condition used in nonlinear acceleration to define the stopping criterion. In this work we implement a coarse-mesh finite difference acceleration for a CFE discretization of the second-order self-adjoint angular flux (SAAF) form of the transport equation and use a postprocessing to enforce local conservation. Numerical results are given for one-group source calculations of one-dimensional slabs. We also give a novel formal derivation of the boundary conditions for the SAAF.

A flexible nonlinear diffusion acceleration method for the S_N transport equations discretized with discontinuous finite elements

Journal Article Schunert, Sebastian ; Wang, Yaqi ; Gleicher, Frederick ; ... - Journal of Computational Physics

This paper presents a flexible nonlinear diffusion acceleration (NDA) method that discretizes both the S_N transport equation and the diffusion equation using the discontinuous finite element method (DFEM). The method is flexible in that the diffusion equation can be discretized on a coarser mesh with the only restriction that it is nested within the transport mesh and the FEM shape function orders of the two equations can be different. The consistency of the transport and diffusion solutions at convergence is defined by using a projection operator mapping the transport into the diffusion FEM space. The diffusion weak form is basedmore »« less
