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?
