SNESSetComputeApplicationContext#
Sets an optional function to compute a user-defined context for the nonlinear solvers.
Synopsis#
#include "petscsnes.h"  
PetscErrorCode SNESSetComputeApplicationContext(SNES snes, PetscErrorCode (*compute)(SNES snes, void **ctx), PetscErrorCode (*destroy)(void **ctx))
Logically Collective; No Fortran Support
Input Parameters#
- snes - the - SNEScontext
- compute - function to compute the context 
- destroy - function to destroy the context 
Calling sequence of compute#
- snes - the - SNEScontext
- ctx - context to be computed 
Calling sequence of destroy#
- ctx - context to be computed by - compute()
Note#
This routine is useful if you are performing grid sequencing or using SNESFAS and need the appropriate context generated for each level.
Use SNESSetApplicationContext() to see the context immediately
