h-multigrid agglomeration based solution strategies for discontinuous Galerkin discretizations of incompressible flow problems

Lorenzo Botti, Alessandro Colombo, Francesco Bassi

In this work we exploit agglomeration based -multigrid preconditioners to speed-up the iterative solution of discontinuous Galerkin discretizations of the Stokes and Navier-Stok…
