Introduction

This online TUFLOW FV tutorial model replaces the previous version, which was included within the TUFLOW FV Manual. The online wiki is designed to be more flexible and easily updated so that the tutorial model are more responsive to enhancements within the software and also based on feedback. Please use the feedback interface at the bottom of each page or alternatively contact support@tuflow.com.

Getting Started

This tutorial has been designed to progressively work through the process of establishing a TUFLOW FV model and running a simulation.

The following user steps are required:

  1. Choose a mesh generator and result viewer
  2. Install the recommended Text Editor software
  3. Download the latest TUFLOW FV executable
  4. Download the tutorial mode dataset
  5. Work through the Tutorial models

Detailed information outlining what data is recommended and where it is available from is provided in the following sections.

Software

TUFLOW FV

TUFLOW FV build 2019-01 (March 2018 release) or later is required for this tutorial model. This can be obtained from the downloads section of the TUFLOW website. It is recommended that you use the latest release version of TUFLOW FV.

The tutorial models can be run without a TUFLOW FV licence.

Choosing a Mesh Generator and Result Viewer

TUFLOW FV requires the user to build and customise their own irregular grid using an external mesh generator package.This mesh can comprise

Whilst there a range of mesh generators available, these tutorials can be developed with your choice of either Aquaveo SMS; or the Rising Water Software GIS Mesher in combination with the TUFLOW Viewer Plugin for QGIS.

More on each of the mesh generation and result viewer packages are provided as follows:

  • Aquaveo SMS (Mesh Generator, Result Viewer and TUFLOWFV Interface) provides you with an environment to build your mesh and also provides powerful data manipulation and pre-processing capabilities. It also has the ability to view, review and post-process results. The SMS Tips page includes useful user information for the software including use of the TUFLOW FV - SMS Interface to assist in building your model.
    To use SMS you will need to download and purchase SMS or alternatively obtain a free evaluation license. Both of these options are available on the SMS Downloads Page. Please note there is also The Aquaveo SMS Community Edition. This free version is similar to the full version of SMS mentioned above but has a reduced set of features.
  • Rising Water Software GIS Mesher (Mesh Generator) The GIS Mesher allows you can build a full mesh completely in your preferred GIS package (Typically QGIS, Mapinfo or ArcMap). It allows the assignment of topography, materials and nodestrings to the mesh all in GIS. It can also read a range of grid formats including *.flt. You can check out some of the GIS Mesher’s functionality here on their Youtube Channel.
    . To use the GIS Mesher you will need purchase the GIS Mesher or alternatively you can use an evaulation license. Both of these options are available on the Rising Water Software Website.
  • QGIS TUFLOW Viewer Plugin (Result Viewer and Model Build Tools) The TUFLOW Viewer QGIS plugin provides you with a series of tools to assist model setup, simulation and result viewing. Please note it does not provide you with the facility to generate a mesh for TUFLOW FV. The Plugin is typically used in combination with SMS or the GIS Mesher to provide a full workflow. You can check out some of the plugin's functionality on our TUFLOW Viewer Wiki Page.

  • So which mesher and result viewer should I use?

    Ultimately it's up to you which set of packages you use for the tutorials. But when making your decision please keep the following in mind:

  • Historically the tutorials have been developed in full version (or evaluation version) of SMS and the tutorial modules can be completed using just this one package;
  • For the GIS Mesher and QGIS Viewer currently only Tutorial Module 1 and 3 include these workflows. Over time we will expand this to include the full tutorial set.

    Text Editor

    A text editor is required for creation of the TUFLOW FV input files. Any text editor can be used for this purpose. However, it is recommended that a more advanced text editor such as one of those listed below be used. Ideally a text editor should be able to:

    • Colour code the TUFLOW FV control file;
    • Open other files from the active control file; and
    • Launch a TUFLOW FV simulation.
    1. UltraEdit: UltraEdit is recommended and can be downloaded for a trial period from www.ultraedit.com. See also UltraEdit Tips.
    2. NotePad ++: NotePad++ is a free text editor. It is available from http://notepad-plus-plus.org/.
    3. See also Notepad++ tips.

    Microsoft Excel

    This is required for editing and working with tabular data and .csv files.

    Results Viewer

    For visualisation of tutorial model results we recommend one of the following options:

  • Aquaveo SMS
  • The TUFLOW Viewer Plugin for QGIS
  • Hardware Requirements

    TUFLOW FV has relatively modest system requirements for small models such as the tutorial model. However, larger and more complex models may have higher hardware requirements - in particular memory (RAM). The tutorial models are designed to be small, to allow for quick simulation and load times. The tutorial model should run on any modern PC or laptop that is capable of running Windows XP or later.

    Recommended Reading

    Whilst the online tutorial is designed to cover as much material as possible, it is recommended that the TUFLOW FV manual be downloaded from the TUFLOW website and be used in conjunction with this wiki.

    Modules

    The tutorial models are presented in a number of modules. The modules have been developed to be undertaken as steps, with each module offering the opportunity to run the model and review the results. New users are advised to undertake the modules in sequence, whilst more experienced users can skip to modules containing specific features of interest.

    Some data is required in order to build and run the models. This includes a digital elevation model (DEM) and aerial photography. The required background model data for the tutorial model is available for download on the TUFLOW website. The download package also contains a working version of the tutorial model for you to refer to.

    Module 1: Simple Trapezoidal Channel

    The first tutorial module introduces the user the TUFLOW FV software. The tutorial works through the steps required to develop a simple mesh model and run a simulation. To access this module of the tutorial please see this page: Tutorial Module 1.

    Module 2: Simple River Bend

    The second module builds a simple river bend model using the TUFLOW FV SMS interface. To access this module of the tutorial please see this page: Tutorial Module 2.

    Module 3: Floodplain Application

    In the third module a real-world floodplain model example is used demonstrate the following:

    • Mesh optimisation
    • Geometry commands (eg breakline commands, region commands)
    • Hydraulic structure commands (weirs, bridges, culverts)
    • Advection dispersion modelling options (salinity, heat, temperature, tracer)
    • Various output processing option

    To access this module of the tutorial please see this page: Tutorial Module 3.

    Module 4: Coastal Application

    In the fourth module is a real-world coastal model example is used demonstrate the following:

    • Application of a sloping water level boundary
    • Cyclone/hurricane modelling using an internal holland wind/pressure model
    • Cyclone/hurricane modelling using an external wind/pressure and wave model
    • Various output options

    To access this module of the tutorial please see this page: Tutorial Module 4.

    Additional Modules

    Additional modules planned include:

    • Module 5 (Three Dimensional Modelling)
    • Module 6 (Sediment Transport Modelling)
    • Module 7 (Water Quality Modelling)
