I don't understand what you're asking. Have you looked at some PETSc examples? You should be able to do this stuff with run-time options. If you are trying something that doesn't work, send the options you ran with and the output. Running with -ksp_view is helpful to see what method is being used. -------------- next part -------------- An HTML attachment was scrubbed...
