In part 1, we went through a few examples of how to identify capacity issues in an model. In this article, we’ll go ahead and fix the issues and learn a few import ICM tricks.

When working with a model, from time to time we’ll need to load background images into the model.
Unlike GIS software, some modeling packages cannot handle large files. In this article we’ll show how to use ArcMap to reduce the size of an image file.
1. the bigger the cell size, the smaller the file size
2. changing the file type might change the compression ratio to reduce the size
3. use a higher compression ratio
4. you can zoom to a smaller area and only export the current extent
NOTE: XPSWMM only supports certain image type. You might need to test a few different options.
This blog is part of the Generative design series. To do generative design we need to run hundreds and thousands of simulations to discovery the best design. In this post, we’ll write the python code to,
The code and example can be found on github.
When designing and operating a collection system, we have two very important tasks.
Traditionally these tasks are carried out by engineers and modelers manually through…
I have blogged about batch import rainfall and hydrograph into XPSWMM using python script with the help of XPX files.
In this article, I will update the batch hydrographs script to import hydrographs from a series of CSV files. The python script can be found at github.
We have hundreds…
Coding is one of my hobbies, I’ll consider it a great day if I can find a way to get my job done by writing a piece of program. The more I write programs, the more I realize building models is very similar to building software.
Updating a calibrated model is one of the most annoying modeling tasks I can think of, not only that it is tedious, it can break the model and lead to hours of frustration trying to fix it.
Here are a few examples,
You might say “I’ve been doing drainage design with rational method, or an SCS design storm for a very long time, why do I need to change?”
That depends on the type of problems you are trying to solve. As many places are getting more urbanized, more and more developed…

How to check the diagnostics file when you see this error swmm error: encountered during 2D initialization, please check diagnostics file.
When running a 2D model, the XP2D engine will write error messages into a a MapInfo GIS file reporting diagnostic information. …
If you’re serious about modeling, you’ll need to understand how the engine solves differential equations sooner or later. So the next time the engine does something strange, you’ll know what to look for.
Most people, I believe, are like me in that they cannot derive their intuition from equations; it…
