An assessment of coupling algorithms for nuclear reactor core physics simulations


By: S. Hamilton*, M. Berrill*, K. Clarno*, R. Pawlowski*, A. Toth n, C. Kelley n, T. Evans*, B. Philip*

author keywords: Multiphysics; Jacobian-free Newton-Krylov; Anderson acceleration; Nuclear reactor analysis
TL;DR: This paper evaluates the performance of multiphysics coupling algorithms applied to a light water nuclear reactor core simulation and compares Picard iteration to Anderson acceleration and multiple variants of preconditioned Jacobian-free Newton-Krylov (JFNK). (via Semantic Scholar)

Convergence Analysis for Anderson Acceleration

SIAM Journal on Numerical Analysis, 53(2), 805–819.

By: A. Toth* & C. Kelley*

author keywords: nonlinear equations; Anderson acceleration; local convergence
TL;DR: This paper shows that Anderson is locally r-linearly convergent if the fixed point map is a contraction and the coefficients in the linear combination remain bounded and proves q-linear convergence of Anderson(1) and, in the case of linear problems, Anderson($m$). (via Semantic Scholar)
