A Moment-Parity Multigrid Preconditioner for the First-Order System Least-Squares Formulation of the Boltzmann Transport Equation

This paper describes a preconditioned conjugate gradient scheme for the Pn-h finite element discretization of a first-order system least-squares (FOSLS) formulation of the Boltzmann transport equation. The preconditioner is based on the norm equivalence between the FOSLS functional and a V norm. Its...
