Dear Matt,

While searcing inside of the petsc bundle, I have seen

PCBDDCMatFETIDPGetRHS
PCBDDCMatFETIDPGetSolution
PCBDDCCreateFETIDPOperators

also there is an example in
petsc-3.5.1\src\ksp\ksp\examples\tutorials\ex59.c

however I could not see it on webbrowser interface. Is this an pre-release
code?
