SNESSetGridSequence#
sets the number of steps of grid sequencing that SNES will do
Synopsis#
#include "petscsnes.h"  
PetscErrorCode SNESSetGridSequence(SNES snes, PetscInt steps)
Logically Collective
Input Parameters#
- snes - the - SNEScontext
- steps - the number of refinements to do, defaults to 0 
Options Database Key#
- -snes_grid_sequence - - Use grid sequencing to generate initial guess
Notes#
Once grid sequencing is turned on SNESSolve() will automatically perform the solve on each grid refinement.
Use SNESGetSolution() to extract the fine grid solution after grid sequencing.
