I didn't see any script for running ex62 in the makefile so I have tried all the runtime combination of options listed in the Paris tutorial 2012 slides (e.g., block jacobi, gauss seidel, uzawa, schur complement, etc). They either give me a zero pivot for LU or errors like Petsc has generated inconsistent data.
