Solution of nonlinear Stokes equations discretized by high-order finite elements on nonconforming and anisotropic meshes, with application to ice sheet dynamics

Tobin Isaac, Georg Stadler, Omar Ghattas

Motivated by the need for efficient and accurate simulation of the dynamics of the polar ice sheets, we design high-order finite element discretizations and scalable solvers for th…

Comparison of Multigrid Algorithms for High-order Continuous Finite Element Discretizations

Hari Sundar, Georg Stadler, George Biros

We present a comparison of different multigrid approaches for the solution of systems arising from high-order continuous finite element discretizations of elliptic partial differen…
