Hi, step-7 (https://www.dealii.org/current/doxygen/deal.II/step_7.html) shows this procedure. Be careful that if you apply Neumann BCs on all your boundary, then the solution is determined up to a constant and you need to add an additional constraint to your solution. Also, you need to satisfy a compatibility condition between the r.h.s. and the neumann data.
