Hello, i'm modelling a network and i'm getting the error Network Unbalanced after input a PRV, i's there a recommendation to insert this valve? If i set the PRV as Inactive the notification do not appear, my pressure upstream it's about 30,0 mH2O and the pressure downstream it's set as 14 mH2O. Besides, it's there any way to check cavitation problems in the Valve?
Hello Fabio,
The following link has information on network unbalanced user notifications: Troubleshooting the Network Unbalanced or Cannot solve network hydraulic equations user notification.
This message would occur with WaterGEMS or WaterCAD, or with the initial conditions calculation in HAMMER. I would recommend reviewing the PRV setting is accurate. Assuming that it is and there are no other issues in the model, you can try making adjustments to the calculation options. Increasing the number of trials is one quick possible solution. Other adjustments like setting the Damping Limit and adjusting the Convergence settings can help. Details can be found in the link above.
Regards,
Scott

Thanks Scott!! I've adjust the number of trials to 5 more and the notification do not appear anymore.
