Dear colleagues, sorry for hijacking the thread, but could you explain to me, how to compute residue of adjoint functional, if possible, with firedrake-adjoint? I've seen in the documentation that |J = Functional(inner(u, u)*dx*dt[FINISH_TIME]) for (variable, solution) in compute_adjoint(J): | provides the solution of adjoint problem, but for residual I need not only solution, but also a set of adjoint equations.

Yes! I opened a github issue here <https://github.com/firedrakeproject/firedrake/issues/1042>. I guess the markdown messes with the python code. Sorry, for that.

Hi Henrik,
That sounds like a bug. Can you create a minimal failing example and file a github issue please?
Regards,
David

Dear all,
If I include
/from firedrake/_/adjoint import */
in my firedrake program, my forward problem does not converge any more. If I do nothing else than loading firedrake_adjoint, should the forward problem not run as before? Note, that I set all the solver options from the command line and not in the program itself. Thus, in the program I just have
/solver = NonlinearVariationalSolver(problem,options_prefix="")// / Thank you! Henrik
