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 SNES context

  • compute - function to compute the context

  • destroy - function to destroy the context

Calling sequence of compute#

  • snes - the SNES context

  • 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
