DMMGSolve
Actually solves the (non)linear system defined with the DMMG
Synopsis
#include "petscda.h"
#include "petscksp.h"
#include "petscmg.h"
PetscErrorCode DMMGSolve(DMMG *dmmg)
Collective on DMMG
Input Parameter
dmmg -the context
Options Database
| -dmmg_grid_sequence | - use grid sequencing to get the initial solution for each level from the previous
|
| -dmmg_vecmonitor | - display the solution at each iteration
|
Notes: For linear (KSP) problems may be called more than once, uses the same
matrices but recomputes the right hand side for each new solve. Call DMMGSetKSP()
to generate new matrices.
