Hi All,
I implement KSP solver in a Newton iteration. The convergence parameters
are: rtol 1.0E-8, abstol 1.0E-50, dtol 1.0E5, maxits 1000.
Does the following convergence monitoring make sense? I thought the
solver should stop before iteration 36, but it stops at iteration 70.
0 KSP

These tolerances use the preconditioned residual norm. You can sue the true
