SNESSetUp#
Sets up the internal data structures for the later use of a nonlinear solver SNESSolve().
Synopsis#
#include "petscsnes.h"
PetscErrorCode SNESSetUp(SNES snes)
Collective
Input Parameter#
snes - the
SNEScontext
Note#
For basic use of the SNES solvers the user does not need to 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().
