I have a network. I’m trying to modify it by adding new elements, and saving it and saving it in the same project but as a different scenario. For instance, in the figure. Left is the original case. Right I included 2 pipes. In the scenario manager, I selected the base scenario, then created a clone (Left figure scenario). I went back to Base scenario and included the pipes. Then, I went back to scenario management and created new scenario (I tried cloning and creating new one).
I run the batch simulation. But when comparing results all the three scenarios are the same one.

How can I have 2 scenarios within one project, but the scenarios have different elements? (E.g. one scenario with more pipes or tanks)
