How can I reduce the number of pipes in my model?Problem ID#: 74797
To reduce the number of pipes in a model try to combine pipes that have equivalent diameters and roughnesses. If you have access to Skelebrator (Tools > Skelebrator) in WaterCAD/GEMS if you have that feature available to you. See more on Skelebrator in the articles linked to further below.
You can also use of Laterals and Customer elements to assign demands along the length of a pipe instead of creating extra nodes (which split the pipe). As of version 10.00.00.50, lateral link elements do not count toward your pipe limit.
Furthermore, you can also use isolation valves instead of valve node elements (like GPVs or TCVs) to model valves, as the isolation valves do not split the pipe.
