Dear developers,<br><br>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. <br>
<br>Please let me know, am I in right way?<br><br>Is there any better procedure in this matter?<br><br>Thanks, BB.<br>
