I am trying to use KellyErrorEstimator of deal.II and I saw various tutorials
which use it. I ran those examples and they work well. Recently, I tried it
with my work and when I print the estimated_error_per_cell vector, all of the
values in that vector are zero.
If you use it for mesh refinement, is the mesh refined? If it is, then your
routine for printing the elements has a bug. If the mesh is not refined, then
what is the solution? If the (finite element) solution is a linear function,
then the Kelly estimator will compute zeros.
I'm afraid there is nothing we can help with from a distance without seeing
the solution and/or the whole code...
