Multiplicative overlapping Schwarz smoothers for Hdiv-conforming discontinuous Galerkin methods for the Stokes problem
We present numerical results for a multigrid method employing overlapping Schwarz smoothers in various V-cycle configurations. The method is based on finite element discretizations of the Stokes problem employing Hdiv-conforming velocity spaces and matching pressure spaces. The method acts on the co...

| 520 | |a We present numerical results for a multigrid method employing overlapping Schwarz smoothers in various V-cycle configurations. The method is based on finite element discretizations of the Stokes problem employing Hdiv-conforming velocity spaces and matching pressure spaces. The method acts on the combined velocity and pressure spaces and thus does not need a Schur complement approximation. | ||
