source: Innovyze Support Portal If you are new to modeling, very quickly you’ll find the peak flow can be different in your graph and your model results summary. How can that be, which one is correct? The difference lies in how the peak flow is calculated. The engine keeps track…

Managing scenarios in a model over a long time is challenging, no matter who does it, what software you use, you might feel hopeless at one point or another. Before the use of a scenario manager, things are much simpler, what you have is all it is, there is no…

source: Innovyze Support Portal When working with models sooner or later you’ll run into a project that you need to prepare data in a really old format from the 60s. And it asks you to prepare everything using a fixed width format. Figuring our how many spaces you’ll need to…

source: Innovyze Support Portal When modeling very large pipes, make sure to break them into segments of a few hundred feet, otherwise, SWMM won’t be able to get the correct results. The SWMM engine assumes the flow rate is the same within each pipe, and we assume a straight water…

source: Innovyze Support Portal When building a 2D model, updating the existing 2D surface is a common task, add more details to the surface, such as adding breaklines for road add proposed structures, such as new buildings, roads and ponds In XPSWMM, you have a few choices: Updating the surface…
