Thanks, I am using SNES and I thought KSPGetConvergedReason() may automaticly checked after each Newton iteration and then the solution is stopped with this message:<br><br> Linear solve did not converge due to DIVERGED_ITS iterations 40<br>
Nonlinear solve did not converge due to DIVERGED_LINEAR_SOLVE<br><br>So how can I tell KSP in SNES to ignore the convergence check?<br><br><br><br><div class="gmail_quote">On Tue, Jan 3, 2012 at 6:58 PM, Jed Brown <span dir="ltr"><<a href="mailto:jedbrown@mcs.anl.gov">jedbrown@mcs.anl.gov</a>></span> wrote:<br>
