Dear Mathew, Thanks for your response!
At line 645 in the source code, http://www.mcs.anl.gov/petsc/petsc-dev/include/petscsnes.h.html , some SNES routines for multi-block solver were listed. Is there any source code for specific testing PDE problem with these routines? In addition, is the KSP version available? Sincerely regards.
