AIR multigrid with GMRES polynomials (AIRG) and additive preconditioners for Boltzmann transport

S. Dargaville, R. P. Smedley-Stevenson, P. N. Smith +1

We develop a reduction multigrid based on approximate ideal restriction (AIR) for use with asymmetric linear systems. We use fixed-order GMRES polynomials to approximate $A_\textrm…
