SNESSetAlwaysComputesFinalResidual#
tells the SNES to always compute the residual (nonlinear function value) at the final solution
Synopsis#
#include "petscsnes.h"
PetscErrorCode SNESSetAlwaysComputesFinalResidual(SNES snes, PetscBool flg)
Logically Collective
Input Parameters#
snes - the shell
SNESflg -
PETSC_TRUEto always compute the residual
Note#
Some solvers (such as smoothers in a SNESFAS) do not need the residual computed at the final solution so skip computing it
to save time.
