[petsc-users] empty split for fieldsplit

[Hoang Giang Bui]

Dear Barry

I made a small example with 2 process with one empty split in proc 0. But
it gives another strange error

[1]PETSC ERROR: --------------------- Error Message
--------------------------------------------------------------
[1]PETSC ERROR: Arguments are incompatible
[1]PETSC ERROR: Local size 31 not compatible with block size 2

The local size is always 60, so this is confusing.
