I should pass a user-defined context, containing element and face local data obtained from PDE solution, to RHS and Jacobian evaluation of SNES process. Here I need to update my context each Newton Iteration. I may pass my context into a monitor function set by SNESMonitorSet. In the monitor function, I cast into my context and update my field (elements and faces) for next evaluations in RHS and Jacobian routines in Newton process. </blockquote>
