  1. Hi Sachi, Thanks for testing the error and finding the work-around. We'll look into it for our next update. Cheers, Chris
  2. Subsequent to this post, ARR have published the Australian temporal pattern information and BoM have released the design rainfall estimates for events up to the 1% AEP. I chatted with Janice Green at the recent Hydrology Symposium. She was optimistic the extreme event design rainfall estimates should go live in February 2017. Here is an announcement from the ARR team: Coinciding with the launch of the IFD the ARR team is happy to announce the release of the temporal patterns for rainfall. Ensembles of 10 patterns are available for each region and 3 AEP bins. More detail on their development is contained in book 2 chapter 5. Also being released is the areal spatial patterns. The temporal patterns are available on the ARR Data Hub and should be accessed at the start of each project. Hydrologic Modelling software is being updated by software developers to do this. Following the launch of the new IFD and remaining design inputs The ARR team is pleased to announce that training programs on the new ARR will commence in February 2017. The training program will feature the key authors of ARR chapters. A full program and dates will be posted on
  3. · Hi All, Two new tutorial modules have been added to the TUFLOW training dataset. Module 9 focuses on multiple domain 2D / 2D modelling. Module 10 details Scenario, Event and Variable options within TUFLOW. These features help efficiently manage and execute projects requiring a large number of simulations. This will be particularly useful for those of you who will be using the new Australian Rainfall and Runoff 2016 ensemble approach to design flood estimation (after the BoM publish Australia's updated design rainfall depths and ARR publish the temporal patterns). The tutorial datasets are available for download from the TUFLOW website: Tutorial Models.aspx The user documentation can be found on the TUFLOW Wiki: Module 9: Module 10: If you have any questions, clarifications or feedback, please email Best Regards, TUFLOW Team
  4. A recording of Bill Syme's recent 1D-2D Modelling Webinar has been upload to the TUFLOW Wiki: Bill provides best practise advice for: 1D channel / 2D domain external linking; Nesting a 1D channel within a 2D domain; Embedding a 1D culvert within a 2D embankment; and Underground pipe network modelling. Happy viewing and stay turned for more webinars coming soon. Chris Huxley
  5. There are a series of upcoming TUFLOW training workshops in Australia, the USA and UK. Location Dates Details Perth (Australia) 16th to 18th August City of Simi Valley (USA) 31st August to 2nd September University of Virginia (USA) 12th to 14th September London (UK) 4th to 5th October Don’t miss the chance to learn TUFLOW directly from the team who develop the software. We teach more than how to use TUFLOW, we also focus on the theory behind it. As always, we encourage open discussion during our workshops. These are great sessions for all levels of experience. New users, or experienced modellers hoping build on their knowledge and understanding of TUFLOW. We look forward to seeing you there, Chris Huxley
  6. The TUFLOW Team have been busy in recent months creating model demonstration and training material. These new datasets will be useful for new users learning the basics and experienced modellers wishing to further develop their skills. A demonstration dataset has been created using over 50 example models to showcase the most commonly used TUFLOW features and model configurations. The models have been categorised under the following topics: - 2D Overland Flow - Output Options - Boundary Condition Options - Topography Updates - Loss Options - Scenario/Event Management - Bridges - 1D/2D Modelling - 1D Operating Structures - 2D/2D Modelling - 2D GPU The models are free to download and run. See the TUFLOW Wiki for more information and download links: A webinar page now exists on the TUFLOW Wiki for sharing useful modelling information: Rachel Jensen has recently uploaded a series of videos which step through Tutorial Module 1. This will be useful for new users. Other webinars also exist on the site that discuss 2D modelling, modelling with different cell sizes and modelling structures. Stay tuned for more video uploads in the future. If there’s anything else you’d like us to add then we’d love to hear your ideas at Happy modelling, Chris Huxley
  7. Dates for the 2016 TUFLOW User Workshops have been announced. In addition to the annual new features workshop aimed at bringing existing users up to date with the latest features, we are also providing computer based training at an introductory and advanced level. Brisbane • Introductory TUFLOW Training: 19th April • TUFLOW User Workshop: 20th April • Advanced TUFLOW Training: 21st April Melbourne • Introductory TUFLOW Training: 10th May • TUFLOW User Workshop: 11th May • Advanced TUFLOW Training: 12th May Sydney • Introductory TUFLOW Training: 24th May • TUFLOW User Workshop: 25th May • Advanced TUFLOW Training: 26th May Click the following link for more information and registration details: Best Regards Chris Huxley
  8. We are pleased to announce dates for the TUFLOW New User and TUFLOW Advanced User 2015 USA Workshops: New User Workshop: May 11th to May 13th Advanced User Workshop: May 19th to May 21st Location: Hyatt Regent (1209 L St, Sacramento, CA 95814) Please refer to the TUFLOW website for the workshop content and cost details: Contact or to register. I look forward to seeing you at the training. Chris Huxley TUFLOW Software Sales and Support (USA)
  9. Ensight is a 3D result viewing software developed by CEI Inc. Ensight can be used for a variety of post TUFLOW simulation result viewing and analysis tasks: 1) Viewing TUFLOW 1D/2D spatial time series datasets (xmdf) 2) Undertaking result dataset calculations 3) Extracting point time series results from xmdf datasets 4) Extracting time varying long-profile data from xmdf datasets 5) Creating animations Some basic user notes have been documented on the TUFLOW wiki: Cheers, Chris
  10. HEC-RAS and FLO-2D model conversion tools have been uploaded to the TUFLOW download page: The user documentation for both utilities is provided in the TUFLOW wiki: HEC-RAS to TUFLOW: FLO-2D to TUFLOW: Cheers, Chris
  11. A new version of the arcTUFLOW tools (2015-01-AA) is available for download from the TUFLOW website: The updated toolbox includes a new tool,“Load Simulation Input Files”. It reads the tlf file and loads all shapefiles to the Map window. It also applies a common symbology to the shapefiles depending on the file prefix. User notes are documented within the ArcGIS section of the TULFOW Wiki:
  12. We are pleased to announce the next round of North America TUFLOW workshops will be run early next year. Two workshop courses will be offered for modelers of varying experience; new users and advanced models. For more information please refer to the training section of the TUFLOW website: If you have any queries, please don't hesitate to email Best Regards Chris Huxley TUFLOW Software Sales and Support (USA)
  13. Hi David, You can control the length of the velocity vector by adding a scale factor entry (-sf) to your syntax. For example: %RUN% -mif -vector -grid10 -t99999 -sf0.5 "C:\mymodel_V.dat"
  14. A picture of the GPU and CPU results may shed some light on the problem. Looking at the flood surface results will tell you more information than PO plots. You say the GPU results are static throughout the entire event? From experience this typically means one of two things: 1) The cell at the PO location is dry (TUFLOW reports the ground level in the PO output in this instance); 2) Downstream boundary issues (drowning out the model). If your PO location is near the downstream boundary of you model it might be worth reviewing the boundary condition definition and inputs in you GPU model. Cheers, Chris
  15. Please ignore this post. The TUFLOW Support team are currently undertaking some tests on the TUFLOW forum. Regards, Chris Huxley
