Already in step-14, similar thing has been done in template <int dim> void
WeightedResidual<dim>::integrate_over_cell (...).
But inside integrate_over_cell it is possible to access fe_values by
cell_data.fe_values because cell_data is passed to this method.
I want to know if it is possible to access cell fe_values by this pointer
inside WeightedResidual<dim>::output_solution () method?
No, this won't work -- neither the WeightedResidual class nor any of its base
classes have an FEValues member variable.
You will have to create such an object wherever you need it. I would suggest
you create it locally in the `output_solution()` function where you want to do
these computations.
