Off the top of my head, the only the I can see is it would be nice to be able to sum the error vector to get the total error estimate. But maybe there's other things already there to do that? On Thu, Oct 11, 2012 at 11:45 AM, Roy Stogner wrote: > > Vikram and I are waffling on this question, so I

[Libmesh-users] ErrorEstimator behavior for goal-oriented problems

2012-10-11 Thread Roy Stogner
Vikram and I are waffling on this question, so I thought I'd throw it out for everybody's feedback: For signed error estimates, e.g. estimates of Quantity-of-Interest error where Q - Q_h ~= sum_E ( \eta_E ), what should the estimate_error() method put in our ErrorVector? The signed eta_E, or the
