Version 4.6

Enhanced 1D results plotting

The process for plotting data from your 1D networks and associated results files has been substantially revised to enable both multiple nodes and multiple results files to be selected in a single operation (calibration files can also be added to plot at this stage as well). The plot definition window has been redesigned to enable this enhanced plotting specification.

Enhanced generic rainfall-runoff boundary

The generic rainfall runoff boundary has been significantly enhanced. It now offers multiple options for each hydrological component, i.e. rainfall, infiltration, transformation, unit hydrograph and baseflow. Furthermore, you can divide a catchment into multiple sub-catchments and define different methods to simulate each. The resulting flows are then combined to produce an overall net flow output, which can be incorporated into a 1D or 2D model as boundary data. The options offered for each hydrological component are globally recognised methods. Thus, this boundary provides a useful alternative to the more UK specific hydrological boundaries already included in Flood Modeller.

Enhanced multi-screen management

Previously, if you generated a 1D data plot on a secondary screen and then reverted to a single screen display, subsequent plots would be created “off screen”. This would require a manual edit of the formsed.ini settings file. Now the Flood Modeller interface checks your setup and positions new plot windows so they are immediately visible.

Enhancements to Flood Cloud

A third option is added for packaging TUFLOW models (i.e. TUFLOW only models and TUFLOW linked models; to Flood Modeller and/or ESTRY). This option is independent from TUFLOW’s in-built packaging functions. It should will provide greater reliability, and in some cases work faster, than the existing options. However, note that it requires a particular model file/folder structure to be setup prior to starting your simulations. This new option is not set as the default option but can be selected in the Flood Cloud settings (TUFLOW tab). An option has been added to allow TUFLOW models to run displaying the TUFLOW native progress window. Note this option only applies when running models locally in test mode. TUFLOW models have been known to “hang” waiting for a user interaction, the prompt for which is only displayed in the TUFLOW native progress window and not in the Flood Modeller general simulation progress window. Thus, the option to display this window in test mode enables users to identify more issues prior to uploading to Flood Cloud (and using credits). The default setting in Flood Cloud does not display the TUFLOW progress window. This setting can be changed either in the Flood Cloud settings window (Options tab) or in the Flood Modeller main interface, in General Settings. Note that activating this setting will also configure your linked test mode simulations to display a separate progress window for the Flood Modeller 1D component of your model.

...and so much more!
