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 SNES

• flg - PETSC_TRUE to 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.
