Hello Bentley ...
I have a model which I imported through the model builder. Can someone please give me a step by step guide on how I can be able to perform hydraulic analysis on the same model using different scenarios by introducing other new pipelines? Or, after simply introducing a new element such as a VALVE/PUMP, how can I set up a new scenario in the same file to accommodate my changes?
My worry is that when I make changes in the new scenario it affects the base scenario.
In the attached file, is it possible for me to create a new scenario in which all the PRVs will be replaced by 5m3 tanks which will act as pressure breakers?adopted.zip
There are a lot of ways of doing this. My preference is to put everything in the base scenario and then make various elements inactive in the child scenarios which I will actually run. For example, make the PRVs inactive in the pressure breaker tank scenarios.
What is the correct approach to do what you have just suggested? Can you kindly please make changes on the attached file so that I can have a clear view on how you've highlighted, arranged the elements in the alternative tree. I tried to create a new child scenario with new child active topologies but unfortunately, elements in the base topology are also affected.
Here is a trivial file that shows what I am doing. The Base active topology has everything. There are two children: one with the PRV branch inactive and the other with the tank branch inactive.

Mulongo, I would strongly recommend going through the Quick Start Lessons in the help, which cover scenario management. If your organization has SELECT, you could also look at the available online training. Here is an article that lists other learning resources.You can also read more about how this works here: Scenario and Alternative Management
Further, here is an article that specifically addresses the use of the active topology alternative. It includes a video demonstration - Active Topology Management
You can look at some of the included example models such as Example5, to see scenarios with different active topology alternatives.

Thank you for the reply. I reviewed the attached model. What I was asking was if the exact position of the PRV in the base file can be replaced with another element lets say a tank in the child scenario without affecting the base topology? I have managed to achieve what I want thanks to your mode. The only difference is that I had to create new pipe links with the new element in the child scenario since the original pipe links when used in the child scenario still stay referenced to the original 'frozen/deleted" base element making the model not to run.
Thank you for the links above. They are very informative and full of information. I went through and managed to understand things better. The help tool is also very useful!
