You may want to try opening the file normally after repairing the database - simply open the WCD file and as long as the repaired MDB file has the same base file name in the same folder, it should open. You can also adjust the global sizes under Tools > Options. When importing the database, you will lose visual settings like color coding and annotations, but you can create them again using the same tools. It does sound like there may have been some corruption in the database and the "repair" option may have cleared that up.
Thanks Marc, I'm glad to hear that you were able to open the model. The Flow(Out) or Flow (Out Net) is the flow leaving the tank and is a negative value.
The Flow(In) or Flow(In Net) is the flow that is being supplied to the tank and is a positive value. If more flow is demanded than is supplied by reservoirs, the deficit is supplied by tank storage. Therefore: Flow Stored = Flow Supplied - Flow Demanded In other words, if more flow is coming from reservoir than is demanded, the surplus goes into tank storage. If it has only inflow at that time, the flow stored will be positive. For example, if you have just one tank which has only outflow at that time, the flow stored will be negative, at that amount.
The "Flow Stored" is the net inflow into tanks at that time. The "Flow Demanded" is the total demand at that time (flow leaving the system), which could be from fixed demands at nodes, pressure dependent demands, emitter coefficients on hydrants, etc. Reservoirs that are filling will experience negative flow supplied. This is mainly reservoirs, but also included negative demands (inflows). The "Flow Supplied" is the total flow rate out of water sources. Flow(Out) for tanks? Problem ID#: 88470 Solution For each time step in an EPS simulation (or for the single time step in a steady state), WaterCAD/WaterGEMS displays the mass balance of flow supplied, flow demanded, and flow stored.
Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley HAMMER Version(s): 08.XX.XX.XX Environment: N\A Area: General Subarea: N\A Problem How is the "Flow stored" calculated in the calculation summary? What is the difference between flow supplied, flow demanded and flow stored? What is the difference between Flow(In) vs.
