Once you have finished creating the model, it is time to run a hydraulic simulation. We recommend running a single period simulation first to check that your model is working as expected. Subsequently perform a 24 hours simulation to get hydraulic results for your network with 1 hour time step.
Furthermore, please, check units setting for the model you have created before starting a hydraulic simulation. Set the unit to liters per second (SI) We will obtain the results for pressure in meters and flow rate velocity in meters per second. To modify these units, click on “Project” in the toolbar menu, then select “Defaults” (see figure below).
In an extended period simulation, it is crucial to adjust “Total Duration” time and “Hydraulic Time Step” to desired values. These parameters can be accessed from the Options section of the data browser by selecting and then clicking “Times” to open the property grid. Thereafter, you should set the value for “Total Duration” time to 24 hr., the “Hydraulic Time Step” to 1 hr. and as a next step run the simulation again (see figure below):
To view the simulation results in a graph form, you need to select the node or link first, then find and click on the graph symbol in the toolbar menu. In the parameter section of the “Graph Selection” window, you have the option to choose between various plot parameters. Select a plot parameter and then click “Ok” to confirm your selection (see figure below):
Another option to view your results is to select a table view by clicking on the table symbol from the toolbar menu (see figure above):
In the “Table Selection” window you have then the possibility to specify the time resulting in a table showing the information of all nodes or links at the selected time (see figure below):
It is crucial to evaluate the results derived from your model. Does the model show plausible results? In case you are not happy with the output, now it is the time for revision. If you think your model is correct, then get ready to answer some questions and introduce your simulation results in the quiz.
