Up to around 10^3. I couldn't say exactly; I've never tried to push those codes to their limits. On second thought, if you're interested in steady flow you can't be interested in very high Reynolds numbers at all, since high Re flow can quickly become oscillatory or turbulent depending on Re and your domain. For a steady flow with a well-defined solution, the formulations in ex13 (modified to remove the mass terms to give you an "infinite timesteep") or ex18 (calling a SteadySolver instead of EulerSolver) should be fine. --- Roy |
