SWMM run anomaly

[jartgo]

I've just started using EPASWMM5 as opposed to the proprietary versions. I can't seem to figure out how to make it run. That is, I can click various sequences of save, run, and map animator and every now and then it will run and produce reasonable results. The times in between, it'll say it ran successfully, but I'll have zero flow for several attempts. Is there a patch, am I doing something wrong, or should I just reinstall it?

I've never heard/read of this problem before. It may be an installation issue, but that would be fairly rare due to the compact code architecture.

You might try posting the *.inp file for review and check out the post "SWMM5 EXAMPLE" (thread162-202765).

OK, I've uninstalled the program, downloaded a new copy from the EPA website, and reinstalled it. The status report (tabular results) is complete after making the run. But I have to run the map animator in order to get any visual results in the profile view. Perhaps the map animator updates all visual results?

Disregard my earlier post. I just figured out that the profile plot is only a snapshot in time...not the maximum HGL. So, when I would initially look at the profile after running the simulation, it was at the start of the event and the system obviously had no flow at that point, and hence no HGL other than backwater. Scrolling through the event in time showed me what I was looking for.

Is there a way to plot the max HGL without scrolling through to a specific time? Although I guess in a large system, the max HGL would actually occur at different times depending on which conduit you were looking at.
