PetscErrorCode  DMMGSolve(DMMG *dmmg)
This is being deprecated. Use KSPSetDM() for linear problems and SNESSetDM() for nonlinear problems. See src/ksp/ksp/examples/tutorials/ex45.c and src/snes/examples/tutorials/ex57.c

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.
