PETSc does not have specific support for staggered grids at this time.
There are a few ways to do it, but none are ideal and we have a proposal
pending in which one item is to improve staggered grid support (but we
won't hear back for several months). If you want to do this, it would be
useful to discuss how to manage staggered grids. The petsc-dev list would
be the best place for those discussions.
