Dear all,<br><br>I'm using Ksp <b>gmres</b> with <b>boomeramg</b> preconditioning and I suspect that even though it converges in preconditioned norm it doesn't converge in true norm, but as I understand <b>KSPSetNormType</b> gmres does not support true residual norm? Is that correct and If it is, is there any other way to monitor the true norm? Do I need to Introduce my own convergence test?<br clear="all">
