  1. We’re interested in hearing your opinion to help guide our future direction: What modelling aspects are important to you? What your model build and result viewing environment preferences are? What you would like to see added to TUFLOW in the future? How you feel we’ve performed over the past 12 months? Please spare 5 minutes to complete the 2019 TUFLOW User Survey: https://www.surveymonkey.com/r/XX5HKC3 Many Thanks, The TUFLOW Team
  2. Our price list was last updated two years ago in early 2017. Our next update will commence on the 1st July, 2019 to coincide with the new TUFLOW Software Upgrades and Support (Maintenance) year. This year’s changes are relatively minor and are as follows. Australian prices are increasing by approximately 5% in line with CPI growth over the past two years. International prices remain unchanged due to changes in international exchange rates with the AUD over the last two years. The TUFLOW FV and HPC CPU threads per licence provision is being made more generous for maintained licences. Previously, the default configuration associated two (2) CPU threads per licence. We will be increasing the thread count provision from two (2) to four (4) per licence at no additional cost. Please note that existing licensees will have their thread count increased (doubled) when they update their licence after payment of the 2019/2020 annual maintenance fee. This change does not affect TUFLOW Classic computations as Classic is not CPU parallelised. The new prices are available via the following links and will come into effect on 1st July, 2019. Any new purchases made prior to 1st July, 2019 will be priced according to the existing TUFLOW price list values. Upcoming maintenance renewals for the period from 1st July, 2019 to 30th June, 2020 will use the new price list values.

  3. Hi Lih, We have seen this behaviour before under the following situations: The output drive where the model is attempting to write results is full. With Windows 10 in particular, if the results are being written to a network location and the network drops out the DOS console window disappears and nothing is written to the .tlf. Do either of these situations sound like they could apply to your case? Can you try rerunning the model after you've changed the output directory so it writes to a your local drive (also after checking it has enough room for the results)? Note, I don't recommend writing results directly to an external hard drive either. I've found it can cause a model to run slower than it would otherwise if the result were written to a local drive. Cheers, Chris
  4. Hi Daniel, The new licence free test and copy options do not progress to the time-step calculations or write check files. A licence is needed for both of those things. If the licence free test confirms the input file references and associated attributes are error free it will return the text "Simulation Start Test == SUCESSFUL" to the tlf and tsf files. If errors are found it will output "Simulation Start Test == UNSUCCESSFUL or STILL RUNNING" instead. If the test is unsuccessful, a valid licence will be required to write the diagnostic output and debug the issue. These new features were primarily created to help users who are running TUFLOW models on the Cloud. The features will let users do final tests on their models before uploading to the compute resource. Similarly, the new licence free package model option was created at the request of some users who run their design simulations on the Cloud. Thanks, Chris
  5. We are pleased to announce the release of TUFLOW 2018-03-AA. The significant items to be aware of in this release are: Substantial simulation speed improvements for large 1D/2D linked models. This update has demonstrated speed increases from 10%, for small simple 1D/2D models, to 4000% (40 times faster!!) for large integrated urban drainage models with over 30,000 1D pit inlets. New licence free model test and copy options. New temporally and spatially varying external stress options (e.g. wind stress). Support for virtual pipes and 1D pipe networks within the same model. TUFLOW HPC now supports all hazard output types. Minor bug fixes. This release is included in the 2017/2018 maintenance period, which was invoiced mid last year. The new executable and 2018 release notes are available for download from the website: https://www.tuflow.com/Downloads.aspx In addition to the 2018 release we have also recently updated the TUFLOW manual. It is now current to the 2017-09-AC release and available for download: https://www.tuflow.com/Tuflow Documentation.aspx. Please refer to the release notes for new commands added since 2017-09-AC. Happy modelling from the TUFLOW Team
  6. Hi Ihsien, Does your TCF include the command "Start 2D Domain" and/or "End 2D Domain". This command is reserved for multiple 2D domain models, and will trigger an M2D licence check, whether you're using multiple domains or not. If these commands are present, delete them (they're unnecessary if you are only using a single 2D domain) and try running the simulation again. Cheers
  7. Hi Tkan, The 2nd and 3rd 2d_rf attributes are applied prior to the Initial Loss (IL) and Continuing Loss (CL) values in the materials.csv. The 2d_rf attributes are primarily designed to enable the representation of spatial variation in rainfall intensity across a catchment, not changes in loss parameterisation. For example, rainfall in the headwaters of a catchment may be more intense than the lower catchment, though still use the same design event temporal pattern. The 2nd and 3rd 2d_rf attributes allow the representation of this variation within the model. Cheers, Chris

  9. Hi Alex, Can you please zip and send a complete copy of your model inputs to support@tuflow.com. Result and check files are unnecessary. We'll recreate them by rerunning the model. We'll identify the cause, email you the fix and also a description outlining how we were able to identify the issue. Thanks, Chris Huxley
  10. We’ve recently received a few support queries reporting TUFLOW has been pausing mid-simulation. In all cases it was due to the new Windows 10 DOS “Quick Edit” option. We’ve added a new page to the Wiki with a solution to the issue: https://wiki.tuflow.com/index.php?title=DOS_Simulation_Paused
  11. The UK TUFLOW Conference will be hosted in Bristol, April 2018. We've designed a short 11 question survey so you can tell us what your interests are. Please click on the link below to have your say and help make this a great event: https://www.surveymonkey.com/r/2018_TUFLOW_Conference Thanks, Chris Huxley
  12. Our September USA training workshop is now fully booked. Sorry if you missed registering.
  13. There's no need for you to merge the datasets in Esri. TUFLOW's data layering functionality will give precedence to the elevation commands lower in the TGC if the datasets overlap on the same cell. We commonly use this feature to "build" topography within a TUFLOW model refining the topography as you progress down the TGC. For example, the order of the elevations commands below will progressively overwrite the topography in overlapping areas to achieve a desired end result. Set Zpts == 100 ! Sets every 2D elevation to 100m for the entire model Read GRID Zpts == grid\DEM_20m_Regional_01.asc ! Overwrites the 100m elevation value where a coarse regional DEM is available Read GRID Zpts == grid\DEM_1m_Refined_01.asc ! Overwrites the above elevation using a refined DEM Read GIS Z Shape == gis\2d_zsh_survey_breakline_004_R.shp | gis\2d_zsh_survey_breakline_004_P.shp ! Updated elevation data for a levee breakline Remember to use your model check files to review the final modelled topography and confirm it is as you were intending. There's information about the check files on the Wiki: https://wiki.tuflow.com/index.php?title=TUFLOW_Check_Files

  15. Hi Chris, Can you please send a copy of both models to support@tuflow.com so we can diagnose the cause? Cheers, Chris Huxley
