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()
.
