SNESSetUp

Sets up the internal data structures for the later use of a nonlinear solver.

Synopsis

#include "petscsnes.h"  
PetscErrorCode SNESSetUp(SNES snes)

Collective

Input Parameter

• snes - the SNES context

Note

For basic use of the SNES solvers the user need not explicitly call SNESSetUp(), since these actions will automatically occur during the call to SNESSolve(). However, if one wishes to control this phase separately, SNESSetUp() should be called after SNESCreate() and optional routines of the form SNESSetXXX(), but before SNESSolve().
