Hi all. I have a problem with my network simulation. In my water distribution network, I have 1 Tank with 1 inlet and 3 outlets. The problem is why the water doesn't flow through the tank? In other word my outlet values always show negative and zero. Can anyone help me? Thanks before.

Hi Alden, I'm looking at tank T-9 and I see that it reaches 100% full and stays at that level. The three outlet pipes are connected to down-stream nodes, but none of them have any demands on them, that I can see, thus the flow out of the tank will be zero. The hydraulic computation is based on a demand driven model(flows are specified/known and hydraulic grades/losses are calculated). If you wish to model demands as a function of pressure you could consider using emitter flows or pressure dependent demands. The former is the easiest to model, whilst the latter provide more advanced capabilities. Regards, Wayne.
