    Jack,

    This is a bit difficult to properly answer without more information or without an image of what your hydrants and node elements look like. If you can post an image example of what your...

    Ross, I emailed you directly and sent you what appears to be the solution. Your control for pump WEST-02 still had conflicting pressure rules closed if above 155 and open if below 155 and this was...

    Ross,

    It is difficult to say for sure without seeing the model or the run report, but in general, a VFD with PRessure based simple controls definitely can be an unstable creation.

    David,

    This definitely is a challenging thing to model hydraulically due to the potential mathematical issues due to multiple tanks closer to one another as described above.

    David,

    Thanks for the further information.

    1) Latest update is 12.4 update 5. We highly recommend updating as soon as you can. There were a few known issues that have been resolved since 12.4...

    David,

    It is difficult to say with the limited information provided and no insight into the system layout, but here are a few initial thoughts:

    Cassandra,

    If you have controls set to be on at 51 and off at 54, your tank appears to be doing just that. If you are unsure, just decrease your output report timestep to 1 minute or if still not...

    Cassandra,

    It is difficult to say with certainty without seeing the model, but what is most likely occurring is that in between your reporting hours the tank is reaching the "on" and "off" levels...

    Ross,

    This has been a known issue in EAPNET since it's initial creation. While there is some newer code that will hopefully address this, that code has not been formally added to the latest...

    Rick,

    How you chose to model anything definitely requires a lot of engineering judgement but ultimately will be the call of each modeler.

    Here are some quick thoughts:

    Iker,

    Forum Support for ICM questions can sometimes be difficult to find. We had a few power users who used to answer a lot of ICM questions that I believe have now retired and this can limit the...

    Monica,

    As it appears EHRA only has H20NET, you would need a stormwater modeling software to do what you are asking for. If you find you might be doing enough of these type of analysis we would...
