Hi. I have a case of extremely slow moving fluid for example x velocity =0.001m/s in this situation what type of boundary should I have on the downstream end. In case of outflow water seems to flow out . I already tried couple of options but the simulation dies within first few time-steps.

What kind of flow is it? is pressure mostly hydrostatic? Whould a pressure BC with the fluid height work?
