SNESSetUp

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

Synopsis

int SNESSetUp(SNES snes,Vec x)
Collective on SNES

Input Parameters

snes - the SNES context
x - the solution vector

Notes

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

Keywords
