Multigrid reduction-in-time convergence for advection problems: A Fourier analysis perspective

H. De Sterck, S. Friedhoff, O. A. Krzysik +1

A long-standing issue in the parallel-in-time community is the poor convergence of standard iterative parallel-in-time methods for hyperbolic partial differential equations (PDEs),…

Monolithic Algebraic Multigrid Preconditioners for the Stokes Equations

Alexey Voronin, Scott MacLachlan, Luke N. Olson +1

We investigate a novel monolithic algebraic multigrid (AMG) preconditioner for the Taylor-Hood (P2​/P1​) and Scott-Vogelius ($\pmb{\mathbb{P}}_2/\mathbb{P…

Multigrid preconditioning of singularly perturbed convection-diffusion equations

M. Shahid, S. P. MacLachlan, H. bin Zubair Syed

Boundary value problems based on the convection-diffusion equation arise naturally in models of fluid flow across a variety of engineering applications and design feasibility studi…
