Ah, you want to do shape optimization. I understand now why you need these derivatives. > I see that in a previous thread > (https://groups.google.com/forum/#!searchin/dealii/tpetra%7Csort:date/dealii/I8aLPu5anrM/gBzaaqivDAAJ), > > you plan on switching over to Tpetra, which will also be useful for us since > we might instantiate those vectors with AD types.

There is a patch here: https://github.com/dealii/dealii/pull/7180 I suspect that it will be merged in the next few weeks or months, but the question is what one can do with these vectors. I'll let Daniel Arndt answer that question, but suspect that additional work is necessary to use them with linear solvers, multiply with matrices, etc. You should already be able to instantiate the other deal.II vectors with AD types, though!
