SNESSetAlwaysComputesFinalResidual#

tells the SNES to always compute the residual (nonlinear function value) at the final solution

Synopsis#

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.
