A scalable multilevel domain decomposition preconditioner with a subspace-based coarsening algorithm for the neutron transport calculations
Fande Kong, Yaqi Wang, Derek R. Gaston +3
The multigroup neutron transport equations has been widely used to study the interactions of neutrons with their background materials in nuclear reactors. High-resolution simulatio…

Nonlinear Diffusion Acceleration of the Least-Squares Transport Equation in Geometries with Voids
Hans Hammer, Jim Morel, Yaqi Wang
In this paper we show the extension of the Nonlinear-Diffusion Acceleration (NDA) to geometries containing small voids using a weighted least-squares (WLS) high order equation. Eve…

A Weighted Least-Squares Transport Equation Compatible with Source Iteration and Voids
Hans Hammer, Jim Morel, Yaqi Wang
Least-squares (LS) forms of the transport equation can circumvent the void problems of other second order forms, but are almost always non-conservative. Additionally, the standard…
