[petsc-users] About DIVERGED_ITS

[w_ang_temp]

    Maybe it is a problem of mathematical concept. I compare the result with the true result which is
 
computed and validated by other tools. I think it is right if I get the same result.

Hello,
 
    I am a little puzzled that I get the right result while the converged reason says that 'Linear solve did not
 
converge due to DIVERGED_ITS iterations 10000'. This infomation means that the iterations reach the maximum
 
iterations. But the result is right now. So why says 'did not converge'? Can I think that the result is right and
 
can be used?


Obviously, your definition of "right" is not the same as the convergence tolerances you are using.

    Thanks.
