High-order matrix-free incompressible flow solvers with GPU acceleration and low-order refined preconditioners

20 Apr 2020 Franco Michael Camier Jean-Sylvain Andrej Julian Pazner Will

We present a matrix-free flow solver for high-order finite element discretizations of the incompressible Navier-Stokes and Stokes equations with GPU acceleration. For high polynomial degrees, assembling the matrix for the linear systems resulting from the finite element discretization can be prohibitively expensive, both in terms of computational complexity and memory...
