+We show the solutions on the initial mesh, the mesh after two
+and after five adaptive refinement steps.

+
+
+Then we show the final grid (after 5 refinement steps) and the solution again,
+this time with a nicer 3d rendering (obtained using the DataOutBase::write_vtk
+function and the VTK-based VisIt visualization program) that better shows the
+sharpness of the jump on the refined mesh and the over- and undershoots of the
+solution along the interface:

+
+And finally we show a plot of a 3d computation.
