Check out AdjointResidualErrorEstimator which computes the adjoint on the same space but then uses PatchRecovery (or whatever you want) on the primal and duals to get an error indicator to drive AMR. Not a great estimate of the actual error, but produces decent meshes for controlling QoI error.
It is on my todo list to tinker with AdjointRefinement indicators for AMR while still preserving the error estimate. > On Feb 2, 2017, at 4:13 PM, Salazar De Troya, Miguel <[email protected]> > wrote: > > Hello > > The current implementation of AdjointRefinementEstimator does a uniform > refinement to obtain an adjoint solution in a richer space.
