We use multigrid +methods on locally refined meshes, which are generated using a bulk +criterion and a standard error estimator based on cell and face +residuals. All operators are implemented using the MeshWorker interface. + +Like in step-12, the discretization relies on finite element spaces, +which are polynomial inside the mesh cells, but have no continuity +between cells. For such functions, we define the mean value and jump operators
