Hello,

I am modelling 3D pipe flow, the pipe is orientated vertically in z-direction. My inlet consdition is consttant pressure at top surface, and outlet is closed. The modelling is converging, however, it shows that at time t=0sec i have fluid velocity already approching to the bottom. Is it beause i have also included gravity affect ? How can i know mass flow rate of the fluid?

Thank you
