Hi, I am trying to use the SNESSetApplicationContext function to set an object as a user application context. This is being done after the SNESSolve was already called once on the SNES object, using a NULL application context. For some reason, after the SNESSetApplicationContext call, the application context on SNES is not being set. I am wondering if maybe I need to set some flag to tell the SNES object to include this new context in further residual and Jacobian calls. I saw the code for the SNESSetApplicationContext function and it doesn't look like it but may be I am missing something ? Thanks for the help. Vijay No virus found in this outgoing message.
