Simulation tab

The simulation tab contains a series of buttons to create new 1D or 2D simulations, or load previously existing 1D or 2D simulations. It also allows you to open the simulation window for simulation files that are active in the Project panel.

New 1D Simulation

This button allows you to create a new 1D river or 1D river/1D urban simulation . It creates and saves a new ief file in order to set up the files and parameters to run a 1D river simulation or 1D river/1D urban simulation. Once you have selected a location and name for your 1D simulation file, it will automatically be loaded into the Project Panel (to the right of the screen) under ‘Simulations’. The default run options will then be displayed in a new window.

New 2D Simulation

This button allows you to create a new 2D, 1D river/2D or 1D urban/2D simulation. It creates and saves a new xml file in order to set up the files and parameters to run a 2D or a 1D/2D linked simulation. Once you have selected a location and a name for your 2D simulation file, it will automatically be loaded into the Project Panel (to the left of the screen) under ‘Simulations’. The default run options will then be displayed in a new window.

New Quality Simulation

This button allows you to create a new 1D water quality simulation . It creates and saves a new qef file (quality simulation file) in order to set up the files and parameters to run a 1D water quality simulation. Once you have selected a location and name for your simulation file, it will automatically be loaded into the Project Panel (to the left of the screen) under ‘Simulations’. The default run options will then be displayed in a new window.

Load Simulations

This button permits you to load existing 1D or 2D simulation files into the Project Panel. The button opens a window where you can browse for a previously created ief/xml file.

When an xml file is loaded, Flood Modeller will automatically create a layer group with the 2D simulation file name and load the GIS files referenced in the simulation file to the Layers Panel. This will allow you to have a look at the area being modelled and verify that the location of the files is valid in the xml file.

Run simulation functionality

Run Simulation

This button starts the currently selected or active model simulation in the Simulations section of the Project Panel. This can be a 1D ief, 2D xml or TUFLOW tcf model file.

Note: A 2D simulation started in this way will automatically use the maximum parallelisation setting. Thus, simulation calculations are shared across multiple parallel threads to maximise simulation speed. The maximum setting for 2D model parallel threads equates to the number of cores within your system.

Prior to running a simulation, the simulation file can then be edited, saved, run and/or closed in its associated model interface window. These are accessed by double-clicking on a simulation in the Project Panel or selecting Open in the simulation’s right-click menu.
