Hello,
I am trying to solve a system whose matrix is of type MatNest. If I
don't use KSPSetUp(), everything is fine. However, if I use that
routine, I get the following error:
0]PETSC ERROR: - Error Message

OK, thank you Matt.

Hi, Junchao,
I have installed the newest version of PETSc and it works fine. I just

I need to solve a 2*2 block linear system. The matrices A_00, A_01,
A_10, A_11 are constructed separately via MatCreateSeqAIJWithArrays and
MatCreateSeqSBAIJWithArrays. Then, I construct the full system matrix
