Model works in EPANET but not so well in WaterGEMS

Hi Guys

Please assist, a user has sent me this for help and I am in transit and unable to assist for the next few hours.

WA corrected controls.ctl  Western Aqueduct_As-Built Current Demands_Rev 5.1.zip

He has a model which he has saved from EPANET (.inp) and imported into WaterGEMS but id does not work as well in WaterGEMS (errors).

Please see the attached (model, control file and screen grabs) and advise further.

Thank you.

  • Hello Linda, 

    While looking at sample models from EPANET I saw that for simple controls on tank in EPANET it is denoted as NODE 1 e.g. not TANK 1. So I replaced tank word with node in EPANET and then exported the file as .NET and then imported in WaterGEMS then controls are imported correctly. 

    After computing the model there are user notifications like junctions are disconnected as tanks become full.

    In WaterGEMS whenever tank becomes empty or full the a built-in altitude valve will close the adjacent pipe., making the network disconnected.

    So you see those user notifications about junctions being disconnected and tanks becoming full. You would need to revise your controls so as tanks not become completely empty or completely full. Please see below technote for reference on this.

    What happens when a tank becomes empty or full? (altitude valve)

  • When I replace the word 'TANK' with NODE the model runs successfully in EPANET but once exported as .inp and imported into WaterGEMS when run a new set of errors come up:

    -1    "(N/A)"    "Action"    "9501"    ""    (N/A)    "Unknown status value in control action (12.140). Value assumed as SETTING."    EPANET import

    ........

    I've tried to search what these refer to but I can't find anything.
