Note the subtle interplay between resolving the corner singularities,
and resolving around the point of evaluation. It will be rather
difficult to generate such a mesh by hand, as this would involve to

-We again look at the meshes first:
+The solution looks roughly the same as before (the exact solution of
+course <em>is</em> the same, only the grid changed a little), but the
+dual solution is now different. A close-up around the point of
+evaluation shows this:
