    Hi Jinlong, You can find more information about this particle error here: User Notification "Initial pressure less than vapor pressure. At the pipe end(s), the elevation(s) or head(s) are incorrect" I do not see any model attached to your forum post…

    This can be an issue when you are pumping downhill with an intermediate high point. When the pump turns off, the downhill section of the pipe will drain by gravity. In some cases with a steep slope the downhill section may never flow full. You should…

    For the attached model, the start pump elevation is 75m, and the other end elevation of this model is 51M. And even compute the initial condition, there will be the message "Pressures below the lowest physically possible pressure in the system at one…
