    How to configure the 2D simulation window to setup an integrated 1D river and 2D simulation


    Article summary

    When your link-lines have been created, a linked 1D river and 2D simulation can be setup.

    A new 2D simulation should be defined and the underlying topography details provided on the ‘Domains’ tab as you would with a 2D (only) simulation.

    Note: You have now referenced the 2D domain details and are ready to run a 2D simulation, however to run an integrated simulation you will also need to reference the 1D river simulation and link-lines as shown below.


    On the 'General' tab, provide the simulation timing details, and check the box to 'Include link to 1D River model'.

    Your 1D river simulation and link-line file are provided on the ‘1D River Links’ tab.

    If you are using a weir link, the discharge coefficient and modular limit can be adjusted globally on this tab. You can also set individual weir parameters for each link line shapefile (that override global values). These parameters are not used with flow or level links. Please refer to the River Links Tab section of the technical reference for further details.

    Ensure you save your simulation to keep any changes. Your integrated simulation is now ready to run. Ensure you use the ADI (default) or TVD solver scheme - the FAST solver is not suitable for integrated modelling.
