Hello,
I have just used the latest version 'petsc-3.3-p4.tar.gz'. The codes which
are ok under version 'petsc-3.2-p7.tar.gz'
are not ok now. The error infomation is as follows. So if can I still use the
original codes without any
modification and also use multigrid with -pc_type gamg -pc_gamg_agg_nsmooths 1.
Thanks.
Jim
