In this month’s tip of the month, Dr. Beccy Haunton, Technical Support & Training Lead, and Aristotelis Liakatas, Flood Modeller Developer, discuss how Flood Modeller allows you to run multiple simulations from just one instance of the User Interface (UI). They explain how to use some features provided in the Flood Modeller UI to further increase your modelling productivity.
Often it is necessary to run a multitude of simulations depicting a variety of scenarios. Flood Modeller provides the option to use event data to easily set up these variations in river networks, and the 1D Simulation Builder enables the automated creation of a suite of simulations utilising this event data. Once simulations have been set up, it is a free choice of the user to run these in whichever way suits them best.
Run in background
Running simulations loaded into the UI is simple – just right-click on the simulation within the ‘Project’ panel, then select ‘Run’ from the drop-down menu. Repeating this, you may start as many simulations as are allowed by your licence (usually 4 if using a Professional Edition licence). Optionally, after starting a simulation, this can be set to run in the background whilst you continue working in the software. This is done simply by closing the simulation window after the simulation has started, then clicking ‘yes’ on the pop-up confirmation. You can then continue using all functionality in Flood Modeller, editing networks, using tools, even setting up and running new simulations!
Run in batch
If you have several simulations ready, the Batch Runner tool provides functionality to run these efficiently. This can be used to run any combination of 1D, 2D and integrated simulations in just 3 steps:
On the ‘Simulation’ tab, click ‘Run Batch’ and the tool will open in a new window.
In the tool, click ‘Add from project’ to fill the table with all simulations in your current project. Alternatively, click ‘Add from file’ to browse to simulations and add them to the table.
Once you have your simulations populated in the table, ensure the ones of interest are ticked. Then click ‘Run Selected’.
Flood Modeller provides various options for running your simulations to allow for flexibility and to suit your specific needs. It is also possible to run simulations outside of the interface altogether. This could be running simulations directly from Windows Command Prompt and/or PowerShell. Alternatively, using Flood Cloud could enable even higher efficiency for running multiple simulations.
