check adjoint value

[casanovamaxime]

Hello everyone,
I have a little question, so far i use the adjoint package in order to perform the minimization of a cost function J and tune a control Function parameter f in order to correct my Navier Stockes operator,
Everything goes well but i do not see in the documentation how to extract the full adjoint state,

If w is my direct state w =[u,p], how do i get the corresponding wadj = [uadj,padj] after the optimization ? so far i compute wadj from a formula but i would like to check with the one of Firedrake,

Thanks for your help,
best,
