Hello Carlos, When the flow through the FCV is less than the setting that you entered, so it is inactive (fully open), like in your case, you get notification because FCV is not working at desired flow setting. For the FCV to work properly it should deliver the set flow not less than that. The below wiki explains about this notification of FCV not delivering the required flow, please go through it. https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/23115/what-is-the-meaning-of-the-notification-valve-cannot-deliver-flow-with-regards-to-a-flow-control-valve-fcv If there is an updated model, please upload it for our review using link mentioned earlier. About red notifications in different time steps, those needs to be corrected for every time step for the model to be stable. If you click on any notification it gives you idea about why notification has been generated and what is the problem with particular element.
