<div><p>Hello Barry,</p><p>Thanks for your reply. The monitor options are fine. I actually
meant my modification of snes tutorial ex1f.F90 does not work and
has some unexpected behavior. I basically wanted to test if I can

Nonlinear solve did not converge due to DIVERGED_LINE_SEARCH

Number of SNES iterations = 8<br>
</p><p>After each "Linear solve converged due to CONVERGED_ATOL
iterations", the code starts to do mymult again. So I thought it
did an extra (unwanted) KSP iteration. I would like to ask if this
extra iteration could be disabled, or maybe I am wrong about it.</p><p>Best regards,</p><p>Yi<br>

How do I see a difference? What does "<span style="font-family: Calibri, sans-serif;">hence ruin my previous
converged KSP result" mean? A different answer at the end of the
