Nitsche's method for discontinuous material parameters

Our proposed method takes carefully into account the discontinuity of the material parameters. The method performs well even in the extreme cases of discontinuity. We also derive a posteriori error estimates that inherit this property. These estimates are able to refine the mesh adaptively without over refinement at the boundary.
