What functionality does the Free edition of Flood Modeller provide?

The Free edition provides the same functionality as the Standard and Professional editions, but it is limited to 100 1D nodes and 100,000 2D cells; across all three 2D solvers (ADI, TVD and FAST).

Is there a restriction on model building in the Free edition?

You can only build 1D models up to the 100 node restriction within the Free edition, however there are no restrictions when building a 2D model.

The Free edition restricts you from running model simulations that are greater than 100 1D nodes and 100,000 2D cells.

Will Flood Modeller work on an Apple machine?

Flood Modeller is designed to work on Microsoft Windows.

What is the recommended computer specification for Flood Modeller

The recommended computer specification for Flood Modeller is detailed below:

  • 1920 x 1080 pixel display
  • Intel Quad core processor 3.2GHZ
  • 8GB Memory
  • 500GB Hard disk space free
  • Windows 10 64bit (Windows 8 is also compatible)

If you are building a dedicated modelling machine, some of the above can be further upgraded. For example, increasing the RAM to 16GB or higher would potentially increase the speed of model runs and provide outputs quicker than if you were to use just 8GB.

With regards to the hard disk, we are often asked whether a SSD should be used. A SSD would provide a slight improvement over a HDD in loading speeds for users adding data into Flood Modeller. However, it wouldn’t improve the simulation speed in any way.

What functionality does my licence provide?

The simplest way to do this is within the Flood Modeller user interface, by clicking on the ‘Start’ tab, then selecting ‘License information’.

Another method is to load the CodeMeter Control Centre and to select ‘Web Admin’. This will open CodeMeter Web Admin within your web browser. Select ‘Licence Monitoring’ -> ‘All Licenses’, and this will detail the available licences.

Why is Flood Modeller opening in the Free edition and not Professional edition?

If you find that Flood Modeller is opening in the Free edition instead of the Professional edition, your licence file will most probably need updating.

Please create a licence file and email it to our support team who will extend the licence validity or support and maintenance expiry date.

If all of the above do not resolve this issue, please double-check that your dongle is being read by your machine within Device Manager (under Control Panel) as your USB may have become faulty.

How do I set up the Flood Modeller-TUFLOW link?

Once you have purchased the software, in order to link the software, Flood Modeller needs to be able to 'see' the TUFLOW engine files. This can be done in two ways:

Option 1

Users should add the location of the TUFLOW files (e.g. C:\TUFLOW\w64) to the [Preferences] section of the settings file formsed.ini (located here: [AppData]/Roaming/Flood Modeller).

There are three options available for this:

  1. TUFLOWPATH=… (this contains an explicit path to the 32 or 64-bit TUFLOW installation)
  2. TUFLOWPATH32=… (this can only contain the path to the relevant 32-bit installation)
  3. TUFLOWPATH64=… (this can only contain the path to the relevant 64-bit installation)

Note: [AppData] is usually located in the C:\Users\<Username> folder. It is usually hidden, therefore you may need to change a setting in your operating system to show hidden folders

Option 2

Users should add the location of the TUFLOW folder (e.g. C:\TUFLOW\w64) to the system path, by adding this path name to the user's PATH environment variable.

Note: The Environment Variables settings can be found here: Start > Control Panel > System > Advanced Tab> Environment Variables

The path to the TUFLOW files can be added to the user or system variables section. However, only one path to a folder containing TUFLOW executables should be contained in the user and system variables section of the Environment Variables window. Therefore, take care to check for PATH variables in both sections. When a new path is added to the path variable it should be separated from the previous path using a “;”.

Once option 1 or 2 has been completed, Flood Modeller needs to be closed (if it was open during the editing) and re-opened in order for the changes to be applied.

You should now be able to start your Flood Modeller-TUFLOW linked simulation.
