ksp - iterative context obtained from
KSPCreate()viewer - the viewer to display the reason
Options Database Keys#
-ksp_converged_reason - print reason for converged or diverged, also prints number of iterations
-ksp_converged_reason ::failed - only print reason and number of iterations when diverged
Notes#
To change the format of the output call PetscViewerPushFormat(viewer,format) before this call. Use PETSC_VIEWER_DEFAULT for the default, use PETSC_VIEWER_FAILED to only display a reason if it fails.
