  3. KSPSetOptionsPrefix calls PCSetOptionsPrefix 

    So we don't need to do so redundantly

  17. Postpone library-level init() as late as possible 

    That way we don't preclude a physics-aware init(Matrix) from user
code.

This will hopefully fix some MOOSE regressions

  18. Got Schur complement fieldsplit working 

    The two last catches:

libMesh::on_command_line didn't work the way I had assumed, so I
replaced it with code that does.

For multiplicative and schur fieldsplits, PETSc really cares what
order you declare fields in.  But we can get arbitrary order by simply
putting everything in a group, because std::map orders groups
alphabetically and libMesh declares group fields in container order.

Commits on Feb 28, 2014

  1. local_variable_indices bugfix 

    This fixes a case of local_variable_indices returning a non-local
index, and adds an assert to see that it doesn't happen again.

-pc_type_fieldsplit works correctly in parallel now.

  1. Postpone automatic NonlinearSolver initialization 

    This should increase backwards compatibility of the petsc_names
changes, and in particular should hopefully fix more of the MOOSE
regressions.
