Definitely use a TransientTerm and see the time step you can get away with. Don't sweep, just use time steps. Using the VanLeerConvetionTerm isn't necessary as the accuracy is not important in a steady state problem. -- Daniel Wheeler _______________________________________________ fipy mailing list fipy@nist.gov http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
