Goal-based angular adaptivity for Boltzmann transport in the presence of ray-effects
S. Dargaville, R. P. Smedley-Stevenson, P. N. Smith +1
Boltzmann transport problems often involve heavy streaming, where particles propagate long distance due to the dominance of advection over particle interaction. If an insufficientl…

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…
