    Dear all,
    In my case, I used the pressure outlet at the circle red zone, but after it ran for a while, it will be diverged. Could you suggest me anything to do in this situation?

    Thank you so much.

    Hello,

    that could be a backflow caused by a strong turbulent vortex. You could use a fringe zone or define in front of an outlet a higher Smagorinsky constant which will laminarize the incoming vortices.
