Hi I have a question...
I'm simulating a line of driving with a pumping system and then occurs by gravity to reach a storage tank therefore the there are sudden change in elevations therefore placed air ejector valves. but at the time of model does not give me results only seem notification ("Cannot solve network hydraulic equations") already refer to various articles related to the notification but can't solve it.
It would greatly appreciate your opinion if it is due to the valves or something I'm not seeing in the method calculation.
Hello Claudia,
As you probably saw in this article, there are many reasons why the network hydraulic equations may fail to be solved. The best option would be for you to send a copy of the model, using these instructions:

Also since you mentioned air valves, if you have multiple air valves with the "treat as junction?" set to "false" and the air valves are open in the initial conditions, see the following articles, with focus on their application on the initial conditions (steady state):
