An Aggregation-based Nonlinear Multigrid Solver for Two-phase Flow and Transport in Porous Media
Chak Shing Lee, François P. Hamon, Nicola Castelletto +2
A nonlinear multigrid solver for two-phase flow and transport in a mixed fractional-flow velocity-pressure-saturation formulation is proposed. The solver, which is under the framew…
Extending Bootstrap AMG for Clustering of Attributed Graphs
Pasqua D'Ambra, Panayot S. Vassilevski, Luisa Cutillo
In this paper we propose a new approach to detect clusters in undirected graphs with attributed vertices. We incorporate structural and attribute similarities between the vertices…
Parallel Element-based Algebraic Multigrid for H(curl) and H(div) Problems Using the ParELAG Library
Delyan Z. Kalchev, Panayot S. Vassilevski, Umberto Villa
This paper presents the use of element-based algebraic multigrid (AMGe) hierarchies, implemented in the ParELAG (Parallel Element Agglomeration Algebraic Multigrid Upscaling and So…
