Hello,
I noticed similar trends in which high Reynolds numbers or presence of bluff bodies in flow path at low Reynolds numbers causing this. Higher residuals in these cases I think is mostly due to the very fact of attempting to solve increasingly unsteady flows with a steady-state solver like simplefoam. |
