Angular adaptivity in P0 space and reduced tolerance solves for Boltzmann transport
S. Dargaville, R. P. Smedley-Stevenson, P. N. Smith +1
Previously we developed an adaptive method in angle, based on solving in Haar wavelet space with a matrix-free multigrid for Boltzmann transport problems. This method scalably mapp…
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…
Angular adaptivity with spherical harmonics for Boltzmann transport
S. Dargaville, A. G. Buchan, R. P. Smedley-Stevenson +2
This paper describes an angular adaptivity algorithm for Boltzmann transport applications which uses Pn and filtered Pn expansions, allowing for different expansion orders across s…
Scalable angular adaptivity for Boltzmann transport
S. Dargaville, A. G. Buchan, R. P. Smedley-Stevenson +2
This paper describes an angular adaptivity algorithm for Boltzmann transport applications which for the first time shows evidence of scaling in both runtime and me…
