In recent years, solvers for finite-element discretizations of linear or linearized saddle-point problems, like the Stokes and Oseen equations, have become well established. There are …
In this paper, we investigate a novel monolithic algebraic multigrid solver for the discrete Stokes problem discretized with stable mixed finite elements. The algorithm is based on the …

Large linear systems of saddle-point type have arisen in a wide variety of applications throughout computational science and engineering. The discretizations of distributed control …
Single-phase flows are attracting significant attention in Digital Rock Physics (DRP), primarily for the computation of permeability of rock samples. Despite the active …
MM Butt - Mathematics and Computers in Simulation, 2022 - Elsevier
In this article, a multigrid solver for distributed optimal control problems governed by time- independent Navier–Stokes equations is presented. A mixed (velocity–pressure) tracking …
