    Hi, I was wondering if I did the "constant flow" method does the pond need to be using Elevation-Area or one of the other options under the volume type that are available? Also i am aware that the solver should be implicit or the GVF-Rational (StormCAD…

    Hi, I have a model in which a pond goes to an outlet structure to go directly to our storm system. However, we want to discard the water quality volume from that same pond to go to arbitrary outfall so it does not affect downstream of our system. I…

    I recommend setting the calculation option Active Numerical Solver to Explicit (SWMM Solvers). I don't see what you described when using that solver.

    No, I do not believe there is a way to customize the data included in the SWMM text output file. However, you should in fact be able to also use the flextable and other tools in SewerGEMS such as element properties, graphs, profiles, etc, to see the results…
