PetscErrorCode PETSCSNES_DLLEXPORT 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_monitor_solution | - 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.
