Anisotropic mesh refinement in polyhedral domains: error estimates with data in<i>L</i><sup>2</sup>(<i>Ω</i>)
The paper is concerned with the finite element solution of the Poisson equation with homogeneous Dirichlet boundary condition in a three-dimensional domain. Anisotropic, graded meshes from a former paper are reused for dealing with the singular behaviour of the solution in the vicinity of the non-smooth parts of the boundary. …
