Runs

A run is used to schedule one or more simulations for processing at the same time.

When a run is set up, one or more time varying inputs are specified for use in calculations. Time varying inputs for wet weather could include one or more rainfall events and flow surveys or time series database objects.

The system creates one simulation for each time varying input therefore each run may contain one or more simulations. In addition, if the run includes any scenarios, and for InfoWorks network only, an episode collection, then simulations will also be created for each scenario and/or each episode for all time varying inputs included in the run.

Create a run

To create a run for an InfoWorks network, right-click a Model Group and select New InfoWorks | Run from the popup menu. The InfoWorks Schedule Hydraulic Run View is displayed.

To create a run for a SWMM network, right-click a Model Group and select New SWMM | SWMM Run from the popup menu. The SWMM Schedule Hydraulic Run View is displayed.

Schedule simulations in a run

To schedule the run:

1. Specify the parameters in the applicable run view:
• InfoWorks Schedule Hydraulic Run View:
  • Enter a run title. If this is left blank, a title will be generated automatically.
  • Select the relevant InfoWorks network and Events or Time Series Data to be run with the simulation.
  • Enter the Start time and date for the simulation. The default is 00/00/00 00:00; this is equivalent to the earliest start time in the event data selected. Alternatively enter an absolute date and time.
  • Enter the required end time or simulation duration, either by specifying an absolute end date and time or by entering a duration relative to the start time and date.
  • Specify other parameters if required.
• SWMM Schedule Hydraulic Run View:
• Enter a run title. If this is left blank, a title will be generated automatically.
• Select the relevant SWMM network and Events or times series data to be run with the simulation.
• Specify other parameters as required.
• If you want to specify a specific start time and date for the simulation, you can do so in the Dates page on the Timestep Contol dialog. The default for a new run is the current date, with a time of 00:00 that can be edited as required. You can also specify an end time if applicable. The default for this is one day ahead of the current date, and with the time set to 00:00. Specify other time parameters such as reporting, dry or wet weather timesteps if required. If no parameters are specified, the default ones will be used for this simulation.
• If you do not want the include the default processes or use the default surcharge method in the simulation, these can be changed in the Options dialog.
2. Click Run simulations. The Schedule Job(s) dialog is displayed.
3. In the Schedule Job(s) dialog select the location to which results will be saved, and the time at which the simulation(s) will be run and click OK.

The run will be scheduled. Details are displayed in the Job Control window.

The progress of the current run is displayed in the Job Progress window.

When the run is complete, the generated simulations will be shown in the Explorer Window under the applicable Run object. See Results for details about viewing simulation results.

The names of the hydraulic simulations generated from the run are in the format XXXXX YYYYY where XXXXX is the name of the scenario (blank for the base scenario), and YYYYY is either the name of a rainfall event/flow survey or 'live data' when using a TSDB. If a simulation has been generated from an episode collection, a number, which corresponds to the order of the episode in the collection, is appended to the name of the simulation in the Explorer Window. Any run that contains both runoff only and hydraulic simulations, the text '_RO' (_Runoff Only) is added to the names of all runoff only simulations in the Explorer Window.

Rescheduling simulations in a run

To reschedule existing simulations in a run:

1. Open the run. Either drag it into the main window or right-click on the run in the Explorer window and select Open from the popup menu. The InfoWorks or the SWMM Schedule Hydraulic Run View is displayed.
2. Click Re-run simulations to re-run the simulations.
   

   Note

   If additional simulations are added to the run (by, for example, adding further rainfall events), the Run simulations button will be displayed, and the additional simulations only will be run. On running the simulations, exclamation marks (!) will be appended to the run title to create a unique name.

   

   Note

   If any other sort of change is made to the run, the link with the existing run will be broken and it will have to be treated as a new run. This is true even if the data is changed back to the original value.

   The Schedule Job(s) dialog is displayed.

3. In this dialog, select the location to which results will be saved, and the time at which the simulation(s) will be run and click OK.

The run will be scheduled. Details are displayed in the Job Control Window.

The progress of the current run is displayed in the Job Progress Window.
