| | ===CityWater Model Runs=== |
|
| |
|
| Pages On WMS that needs to be done:
| | When performing model runs with CityWater, it is common to see a lag in the amount of time it takes to process the run. When there are too many runs to perform simultaneously, CityWater uses a scheduling system to sort the model runs. To ensure that each product can get processed effectively without crashing, CityWater was designed to organize each run into a waiting queue which can be the cause of longer run times. |

| | '''Three reasons why run times might be longer:''' |
|
| |
|
| Basin Data...
| | 1. Writing the results to the database – CityWater must be able to access results. Therefore, some of the time used to execute the run goes towards writing the results to the database so that the CityWater app can find and access the data that is needed. |

|
| |
|
| Routing HEC-1 Cards dialogs include:
| | 2. Performing extra analysis – One of the reasons it takes CityWater longer to run than in Epanet is because CityWater has to generate the zone, pressure swing, and peak-day fire flow layers which aren't offered in Epanet. This creates a longer wait time for each run. |
|
| |
|
| Routing Data...
| | 3. Generating the visualization layers – CityWater uses visualization layers to display the model on the map which takes more time to generate and leads to a longer run time. |

| | '''Running Scenarios''' |
|
| |
|
| | Since not all of the steps above are necessary while running scenarios, it is more common for a scenario to run faster than the initial upload. Running the scenario, however, should take roughly the same amount of time as it would for the initial model upload. Both the number of pipes and the number of time steps contained within the model will increase the amount of time it takes to run the model. This is due to the fact that the size of the model increases accordingly. The suggested amount of pipes for a given project is roughly around 10,000 to 15,000 pipes and 100 time steps. At this time, CityWater best performs under these parameters. |
|
| |
|
| | '''Ways to better the outcome of larger scale models:''' |
| | |
| | [[File:CityWater_Project_Details.PNG|700 px|Example of the Project Details page]] |
| | |
| | 1. Reducing the number of pipes within the model – An accurate Epanet model is not always contingent on a high number of pipes. Therefore, it is likely that reducing the pipes in a the model will still be effective. |
| | |
| | 2. Reduce the number of time steps within the model – When working with a larger model, it might be effective to reduce the typical 24 hours with a 15 minute time steps to an hourly time step over a span of 24 hours. |
| | |
| | 3. Use the Viewing options – In a model, the exclusion of the Scenario, Fire Flow, or Schematic add-ons could benefit the project. With use of only the visualization capabilities, the model can still function, even with larger projects, because they are not highly influenced by the size of the model. |
