  Anisotropic Meshes for Resolving Edge Singularities and Boundary Layers
Thomas Apel (TU Chemnitz)

Anisotropic meshes are characterized by elements with a large or even asymptotically unbounded aspect ratio. Such meshes are known to be particularly effective for the resolution of directional features of the solution. In the talk, we characterize suitable anisotropic meshes for approximating edge singularities in various elliptic problems and boundary layers in singularly perturbed problems.

In solving the Stokes or Navier-Stokes problem the question arises which pairs of elements are stable independent of the aspect ratio of the elements. For several pairs of elements positive and negative results are given.
