  3. Hi Rvan Can you please email support@tuflow.com the model input files and the .tlf file, or if too large just the .tlf file to start with and we will help you solve the problem. In regards to the overlapping materials, the material polygon that is being read into TUFLOW last will set the material for the location where it is overlapping. For material polygons within one layer we recommend to remove the overlaps to be sure straight away which material is applied. Kind Regards, Pavlina
  4. I am going through a model that is modelling flow down a 4% - 7% grade and the results are showing Sub-critical flow with Froude ~ 0.6 - 0.8. When I do simple hand calc checks I am expecting Froude to be up around 2.0 ? What could be impacting the model. I have noticed that one of the materials layers has two overlaping surface roughness definitions? How is this resolved ?
  5. Hi, I appreciate it's quite a late reply, but after a few of these types of queries, we've put together the following guidance on Flood Modeller-ESTRY linking:- https://wiki.tuflow.com/index.php?title=TUFLOW_1D_Flood_Modeller_Connectivity Cheers, Duncan
  6. We've put together some scheduled training courses for 2020. There'll be introductory courses in Leeds and London in March and October. We'll also be holding some new release hands on training in February to go over the details of modelling with the exciting new functionality which will be available in the 2019 release of TUFLOW. Spaces will be limited. http://www.tuflow.com/Training.aspx?ubt Email training@tuflow.com if you have any questions or would like to register.
  7. Hi Lizzie, This functionality is not currently available, however is on the development list and hopefully something that will be added soon. Thanks for your suggestion Thanks, Ellis
  8. Hello, I don't know if it's already available (or if not if this could be logged as a feature request) but is there a way when viewing TUFLOW results in QGIS using the TUFLOW viewer plugin, to be able to hover over e.g. your water depths in the plan view and get the water level value to be displayed? (I suppose a bit like the QGIS value tool plugin). Thanks, Lizzie.
  9. Hi Richard, There are only two possible options available at the moment - classic or 1D weir as the global factor is not supported in HPC yet. Knowing that your HPC model is going to be large you might need to play with the 1D weir and conduct some sensitivity testing. Kind regards, Pavlina
  10. Hi, I have an HPC model (for a rating curve review) with a 2d weir in it that I'd like to change the weir factor for. Since 'Read GIS WrF' isn't in HPC yet what would you suggest? Obvious options are: Try in classic - this current model will feed in to a larger HPC model and this option won't be available there, so that doesn't seem like a great way forward. Use a 1d weir - I have tried this, with unsatisfactory results. If nothing comes of this post then I will try again here. Use a global factor - worried about this affecting the model in other places - would probably not be transferable to the larger model. Thanks,

  12. Hi all, I am simulating a direct rainfall model, there is several deep slope embankments locating within the model. Once the rainfall begin to be started I suddenly get large depth (0.3m roughly) on the embankment surface, this does look very strange especially as there has only been small of rainfall on the catchment when they start appearing. Can someone know the reason and solve this issue ? Thanks for any help !
  13. Hi. Are there any places left for the Melbourne tuflow course? Cheers.
  14. I found this topic very interesting but unfortunately I do not get what PHA means with "HX wings" as I only have used wings in the 1D cross sections when there are instabilities and the grid size is fairly small (like 2m or so). Could anyone upload an schematisation please? The way I would do it is extending the HX to be snapped to the CD polygon as the best representation comes from having the same/approximately width in 1D and 2D but also the same or similar elevation at the end of the CN line (to account for the top of bank). I generally use a zln_TOB (top of bank) layer to impose the elevations I have in surveyed cross sections but I also get elevations from my LiDAR in between and for interpolates. I will be looking forward to know if the applied schematisation is the same as the one I would use. I am always eager to learn and improve Regards to all, Monica
  15. Hi All, I was wondering if you can let me know what is the command in asc_to_asc tool that can be used to remap a lower resolution flood map using a higher resolution DEM? Thanks
  16. The TUFLOW team, together with our long-term collaborators, Edenvale Young, have been planning the 2020 UK TUFLOW Conference. The dates have now been finalised and we are pleased to announce that the 2020 UK TUFLOW Conference will be returning to Bristol and the world-renowned Bristol Zoo, on Tuesday 30 June and Wednesday 1 July. If you have an exciting TUFLOW application that you would be interested in presenting then please contact us at info@tuflow.com to register your interest. We’ll be releasing more details later in the year.
  17. Dear TUFLOW community, I am having a big problem with the projection and visualisation of the produced grids by my 1D2D linking model and I am a bit desperate as I do not find much information about it. I have included "asc" within the "Map Output Format" to get the ascii files created by the model. However, when I am analysing the ascii results I observe they do not match the grid created by the model (see image below). I have a grid of 6 m set up in the tgc but the results suggested a smaller grid. The projection within the tcf is described with a coordinate system such as "CoordSys Earth Projection xxx". All the information within the model including the DEM files are in the same projection therefore I do not understand this. I have also produced the ascii files using a bat to produce them from the xmdf files but this does not make a difference. I do not know what to do since I have never seen this before. The model was inherited but I have not seem any anomaly in the model schematisation so far. I would really appreciate help with this topic since it is urgent (I cannot properly assess water depth for example) and looking within the manual I did not find any answers, neither in Internet. Thank you very much in advance, Monica
  18. Hi There, I am running a fairly large rain on grid model and initially thought about multiple domains to reduce run times but this isn't available with the hpc solver yet. Is it possible to extract the hydro graphs at the intended 2D2D boundary (using a coarse grid model) and then use this as an input into a separate fine grid model? I imagine this would essentially mean a hydro graph for every coarse grid cell along the boundary. Many thanks
  19. Old thread alert! However, it seems a good place for the following... I wonder if we could have quite the opposite of what I first asked for way back when, and have an option to make the copied model much larger! This time, by looking in the place where model results would be being written, if the simulation was actually happening, and if there is anything there (with the right name) then copy that into the copy of the model. Just to make things easier to bundle up together for issue. It may be that this would fit much better with the -pm option, rather than -c, but I'm still a little wary of -pm as it's done the occasional funny thing when dealing with a model with lots of scenarios (while -c will always perform flawlessly). Alternatively, perhaps a completely separate utility that just goes and gets the results (I don't always want another copy of the model, I just want the results collated) ight be a good idea..? Thoughts very welcome! It may be that there's some neat and clever way of doing the above already? I normally just do it manually, but copying a few files from the main Results/ folder, then some from plot/, then csv/ and gis/, then the .flts from grids/ all gets a little tedious! So anything to speed up the process would be appreciated. Thanks! Peter.
  20. ...but your max and min will be at the start and end of your simulation, as the model only permits the groundwater to fill up at present.
  21. 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
  22. Hi Monika, TUFLOW doesn't do any datum transformations, so everything that you specify needs to be relative to a consistent datum of your choosing. So yes, your boundaries and bathy all need to be using the same datum, and the outputs will then also be relative to that same datum. I hope that helps, Peter.
  23. Hello All, I am confused about a thing. Does TUFlow has any reference for the output? I mean, water level that I get as model output is based on which reference/datum? Does it depend on the input boundary datum? If I provide water level data as upstream and downstream boundary condition, I guess I need to maintain same datum. Do I also need to have the same datum as water level for the bathymetry data that I use to prepare the domain? Thanks
  24. The 2019 TUFLOW Release Australian Workshops start in a few weeks, and this year’s release is a big one so if you're interested signup soon as there are limited places remaining. The dates of the courses are provided further below and on our training page. To register download the flyer or email training@tuflow.com. The 2019 release is another game changer off the back of last year’s highly successful TUFLOW HPC engine release. This year there are major enhancements to the HPC engine and other exciting developments including: · Quad-tree mesh resolution refinement · Sub-Grid Sampling (SGS) that utilises the finer detail of the underlying DEMs/TINs in the hydraulic calculations · A new sub-grid turbulence scheme that has minimal cell size dependency · Non-Newtonian flow for modelling slurry and tailings dam failures · The TUFLOW Viewer GIS tools · Numerous new minor features Quad-tree refinement offers substantial benefits allowing you to very easily have finer cells where the hydraulics and topography require those extra levels of resolution (or coarser cells in areas that don’t need high resolution). Sub-Grid-Sampling (SGS) in combination with the new sub-grid turbulence enhancements is proving to be a game changer for fixed grid modelling. For whole-of-catchment models (e.g. direct rainfall models), the response times are quicker and water retention substantially less, especially where the DEM resolution is much finer than the cell size. For deep sided smooth channels, for example a concrete lined trapezoidal channel, that are not mesh aligned the flow patterns no longer have “saw-tooth” effects and now closely obey Manning’s formula. Sensitivity of results to mesh size is greatly reduced and effects due to rotation of the grid almost eliminated. This is far-reaching in that TUFLOW HPC is now able to produce the same quality of results as a well-designed, high resolution, flexible mesh construction, even if using a coarse cell size. The release workshops will provide detail on the new features and the hands-on computer-based training the day following allows you to apply the new features to models. Due to over-subscription of our introductory training courses in the middle of this year, we’re also offering another round of introductory courses the week prior to the release workshop/training. 2019 Release Workshop Schedule and Details Location Introductory Training (computer based) 2019 Release Workshop 2019 Release Training (computer based) Brisbane 15 - 16 October 22 October 23 October Sydney 5 - 6 November 12 November 13 November Melbourne 26 - 27 November 3 December 4 December Introductory Training Two-day computer-based training that is aimed at new TUFLOW modellers.
