SNESFASFullSetTotal#

Use total residual restriction and total interpolation on the initial down and up sweep of full SNESFAS cycles

Synopsis#

#include "petscsnes.h"  
PetscErrorCode SNESFASFullSetTotal(SNES snes, PetscBool total)

Logically Collective

Input Parameters#

  • snes - the SNESFAS nonlinear multigrid context

  • total - whether to use total restriction / interpolatiaon or not (the alternative is defect restriction and correction interpolation)

Options Database Key#

  • -snes_fas_full_total - Use total restriction and interpolation on the initial down and up sweeps for the full SNESFAS cycle

Note#

This option is only significant if the interpolation of a coarse correction (MatInterpolate()) is significantly different from total solution interpolation (DMInterpolateSolution()).
