Coarsening and parallelism with reduction multigrids for hyperbolic Boltzmann transport
S. Dargaville, R. P. Smedley-Stevenson, P. N. Smith +1
Reduction multigrids have recently shown good performance in hyperbolic problems without the need for Gauss-Seidel smoothers. When applied to the hyperbolic limit of the Boltzmann…
A comparison of element agglomeration algorithms for unstructured geometric multigrid
S. Dargaville, A. G. Buchan, R. P. Smedley-Stevenson +2
This paper compares the performance of seven different element agglomeration algorithms on unstructured triangular/tetrahedral meshes when used as part of a geometric multigrid. Fi…
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…
