[petsc-dev] DMMG being deprecated

[Barry Smith]

    PETSc-developers,

       I have marked the DMMG routines as being deprecated in PETSc, they will be in the next release but then removed before the release after next. 

      The functionality of using the DM in the solution process (for example with multigrid or grid sequencing) is being moved into KSP and SNES (and eventually TS also). Much of it is in place and there are some examples: look for examples that use KSPSetDM() or SNESSetDM().

      Please send questions etc to petsc-dev at mcs.anl.gov expecially for functionality that DMMG supports that is not yet in KSP or SNES.
