PetscErrorCode DMMGCreate(MPI_Comm comm,PetscInt nlevels,void *user,DMMG **dmmg)
Collective on MPI_Comm

Input Parameter

comm - the processors that will share the grids and solution process
nlevels - number of multigrid levels
user - an optional user context

Output Parameters

- the context - Notes: To provide a different user context for each level call DMMGSetUser() after calling this routine
