Depending on your formulation (and on the mesh - straight would be safer than curved, for example) it would be possible to for a code to generate the wrong gradients but still leave you with a formulation with the right answers. But I would *very much* like to know that you're still getting the right analytic solutions with r4611. That looks mathematically correct and it fixed the problems with our app code, but I haven't run any benchmark problems on it yet. > I don't have time to check for myself right now... but I'll > certainly investigate more on Monday.
