SNESSetApplicationContext

Sets the optional user-defined context for the nonlinear solvers.

Synopsis

#include "petscsnes.h"  
PetscErrorCode SNESSetApplicationContext(SNES snes, void *usrP)

Logically Collective

Input Parameters

• snes - the SNES context

• usrP - optional user context

Notes

Users can provide a context when constructing the SNES options and then access it inside their function, Jacobian, or other evaluation function with SNESGetApplicationContext()

To provide a function that computes the context for you use SNESSetComputeApplicationContext()

Fortran Note

You must write a Fortran interface definition for this function that tells Fortran the Fortran derived data type that you are passing in as the usrP argument.
