| Topic | Multigrid Methods for Vector Field Problems | ||
| Contents | We design and analyze V‐cycle multigrid methods for problems posed in H(div) and H(curl). Due to the fact that traditional smoothers do not work well for the vector field problems, a special approach for smoothers in the multigrid methods is essential. We introduce a new smoothing technique which involves non-overlapping domain decomposition preconditioners based on substructuring. We prove uniform convergence of the V‐cycle methods on bounded convex hexahedral domains. Numerical experiments that support the theory are also presented. | ||
