Hi, I'm getting a KSP_DIVERGED_INDEFINITE_PC error using CG with ILU. I tried increasing the number of levels of fill and also tried other options described in http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/PC/PCILU.html but without any luck. Are there some other preconditioner options that might work? The solution converges nicely with petsc's cg + lu and sparskit2's iluk on an independent cg serial solver.
Thanks, -- Hugo Gagnon -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.mcs.anl.gov/pipermail/petsc-users/attachments/20130420/60dd2304/attachment.html>
