Chebyshev smoothing with adaptive block-FSAI preconditioners for the multilevel solution of higher-order problems

Pablo Jiménez Recio, Marc Alexander Schweitzer

In this paper, we assess the performance of adaptive and nested factorized sparse approximate inverses as smoothers in multilevel V-cycles, when smoothing is performed following th…

A Parallel-in-Time Combination Method for Parabolic Problems

Michael Griebel, Marc Alexander Schweitzer, Lukas Troska

In this article, we present a parallel discretization and solution method for parabolic problems with a higher number of space dimensions. It consists of a parallel-in-time approac…
