We have set up a distribution model with 4 pressure zones and multiple zone boundary valves between zones. We cannot seem to get the zone boundary valves to operate as they do in reality. Currently zone boundary valves include two valves at each location one set to allow flow if the upstream pressure is met and one to allow flow if the downstream conditions are met. This works for steady state modeling but under EPS modeling we get all kinds of unbalanced errors. The program also looks at the previous run to help set up the next run. So the reservoirs in the upper zones are depleted as the water moves to the lower zones and wells in the lower zones are never called to start. I was wondering if anyone else experienced anything like this.
