An agglomeration-based massively parallel non-overlapping additive Schwarz preconditioner for high-order discontinuous Galerkin methods on polytopic grids
P. F. Antonietti, P. Houston, G. Pennesi +1
In this article we design and analyze a class of two-level non-overlapping additive Schwarz preconditioners for the solution of the linear system of equations stemming from discont…

V-cycle multigrid algorithms for discontinuous Galerkin methods on non-nested polytopic meshes
P. F. Antonietti, G. Pennesi
In this paper we analyse the convergence properties of V-cycle multigrid algorithms for the numerical solution of the linear system of equations arising from discontinuous Galerkin…
