[petsc-users] Does this mean the matrix is ill-conditioned?

Hi, all,
The following is the output from the solution of a Poisson equation
from Darcy's law.
To compute the condition number of matrix, I did not use PC and use
GMRES KSP to do the test.
It seems like that the condition number keep increasing during the
iterative solution. Does this mean the matrix is ill-conditioned?
For this test, it did not achieve convergence with 10000 iterations.
When I use BJOCABI PC and BICGSTAB KSP, it generally takes about 600
times iteration to get the iteration convergent.
Any suggestion for improving the convergence rate will be much
appreciated. The solution of this equation has been the bottleneck of
my code, it takes more than 90% of the total time.
Thank you very much.
Best Regards,
Kai
