Runs and Simulations

Simulation results from runs can be viewed in the GeoPlan Window, the Results Graph / Grid Window and the Network Object / Results Grid Window of the Network page.

There are two types of runs in ICMLive Operator Client:

• Manual run
• Automatic run

Note: A licence is required for running simulations in Autodesk ICMLive Operator Client. See Simulation Licence for details.

Both manual and automatic runs can be observed runs or full runs (see below for definitions).

Automatic runs can be scheduled or externally triggered.

Simulation results are viewed in the Network page and are selected for viewing from the Run Window whereas the run type and status are both shown in the Server Simulation Schedule Window.

Note: ICMLive manual and automatic runs cannot be deleted within ICMLive Operator Client. Deletion can be performed in InfoWorks ICM Ultimate or ICMLive Configuration Manager.

Manual runs

A manual run is a run that is created ad hoc by users from the ICMLive Operator Client interface, via the Run Window. The Run properties section of the dialog allows users to specify run properties such as start time, run origin, end time, whether the run us a full or an observed run, etc. It is important to note that action generation is turned off by default for manual runs but that it can be turned on (or off) on the Run window.

The Simulate run link of the Run operations section can then be invoked to actually initiate the run.

Tip: Generating manual runs can be permissioned in InfoWorks ICM Ultimate or ICMLive Configuration Manager and therefore may not be available to ICMLive Operator Client users who have not been granted rights to perform this operation. If this is the case a warning message will be displayed.

Automatic runs

There are two types of automatic simulations:

• Scheduled – Automatic simulations may be scheduled per the existing manifest run schedule set in ICMLive Configuration Manager. A higher run frequency for automatic simulations may be triggered by the occurrence of an alert or by manually setting the Alert Trigger in the Server Simulation Schedule Window or from the Manifest toolbar. See Alert Triggered Runs for more information.
Note: Automatic scheduled runs cannot be created or altered by the user.
• Externally triggered – Automatic simulations may be initiated through a third party application by modifying a trigger file that is defined the manifest run schedule in InfoWorks ICM Ultimate or ICMLive Configuration Manager. If externally triggered simulations are not desired, simply do not specify any trigger file in the manifest object in InfoWorks ICM Ultimate or ICMLive Configuration Manager. See Externally triggered runs for more information.

Automatic scheduled runs are created and added to the InfoWorks Agent Simulation queue by the Innovyze Live Server according to the schedule specified on the related manifest in InfoWorks ICM Ultimate or ICMLive Configuration Manager. See the InfoWorks ICM help for further details.

Observed runs versus full runs

An observed run only carries out the rainfall runoff calculations for a model. Because no hydraulic calculations are performed these simulations are extremely quick.

To perform an observed run, generate the run as any other run in the Run Window and enable the Observed run option in the Run properties section.

On the other hand, when a full run is carried out, both rainfall and hydraulic calculations are performed, therefore this type of run is more-time consuming. Manual full runs are created in the same way as manual observed runs except that the Observed run option should not be enabled.

The idea behind these two run types is that observed runs are intended to be performed most of the time, with a full model run only carried out less frequently, once a day for example. Observed runs may trigger a full model run if the data causes an alert and a trigger has been set for the corresponding alert category. Observed runs will incorporate observed data in their result output, so allowing alerts to be set on observed data (such as time series data).

Variant runs

Variant runs are used to carry out simulations using networks based on a baseline network. Multiple scenarios can be run in order to model different responses to the occurrence of an event in the baseline model.

Variant runs can be scheduled to be carried out whenever a full run is performed, or the runs can be scheduled to be triggered by an alert raised by the baseline simulation.

See Baseline and Variant Runs for more information.
