  3. Hi Kian, Using half the smallest cell size (e.g. 1 second) would be a safe starting point, the solver will adaptively change it. Cheers Phil
  4. We are pleased to announce a beta release of TUFLOW Classic/HPC 2020-10-AB. We are releasing initially as a beta with the intent to finalise during June 2021. This public beta release is a substantial update to the 2020-10-AA version that includes a range of enhancements and bug fixes. Included are a few of the new features for the 2021 release that are ready for application and we are seeking feedback on. Operational control enhancements to allow operational control channels to other control channels, making coordinated operations possible. New SGS processing approach that: Samples material layers to carry out a parallel channel analysis across cell faces Removes issues with elevation datasets that cover part of a 2D cell Allows for high resolution raster output Detection of SGS cells which may require a breakline Support for output zones in Quadtree Ability to reduce groundwater levels over time Support for 12DA supertins Ability to spatially vary weir factor in the HPC solver Ability to user define hazard categories based on a depth, velocity and depth-velocity thresholds HPC stability improvements for models with depth varying Manning’s n values Non-Newtonian flow enhancements for the HPC solver The new executable and the release notes are available for download from: https://tuflow.com/downloads/#tuflow. This release is included in the 2020/2021 maintenance period, for any licensing queries, please contact sales@tuflow.com. An update to the TUFLOW manual is progressing and when released will be aligned with the 2020-10-AB version. Happy modelling from the TUFLOW Team and as always, any queries, suggestions or issues, please don’t hesitate to contact support@tuflow.com. Best regards The TUFLOW Team
  5. Hi Ryan, In order to be able to access the TUFLOW licence server, you will need to have setup you machine to access this, as per this instructions on the wiki: https://wiki.tuflow.com/index.php?title=Wibu_Dongles#Configuring_Access_to_Network_Licence As is sounds like you are not in the office, you will likely need to be on a VPN to tunnel into your work network. Regards Phil
  6. We are pleased to announce the release of TUFLOW Classic/HPC 2020-10-AA. This release is a substantial update to the 2020-01 release that includes enhancements to the HPC and Quadtree solvers and new default settings. HQ boundaries in HPC and Quadtree now default to the same approach as used by Classic solver Dambreak piping failure and new 1D dambreak channel Automatic adjustments of 1D structure losses according to the approach/departure 2D velocities Two new layered flow constriction approaches for improved modelling of pressure flow at bridges A range of bug fixes primarily relating to the new functionality in the 2020-01 release The new executable and the 2020 release notes are available for download from: https://tuflow.com/downloads/#tuflow. This release is included in the 2020/2021 maintenance period, which was invoiced mid year, therefore licences will need to be updated for the 2020/2021 period. For any licensing queries, please contact sales@tuflow.com. An update to the TUFLOW manual for the 2020 releases is now underway, but in the meantime the 2018-03 release version of the manual is the latest and should be read in conjunction with the 2020 release notes. Happy modelling from the TUFLOW Team and as always, any queries, suggestions or issues, please don’t hesitate to contact support@tuflow.com. Best regards The TUFLOW Team

  9. This indicates that there is a Quadtree cell for which more than 1 water level boundary (HT, HQ, HX or QT) is being applied. There should be a spatial messages in the _messages GIS file which locates the cell.
  10. Ok thanks. I'm implementing the approach mentioned in my previous post. If possible can I send you a beta version over to test that it works on your system? If you are happy to beta test can you please send me an email at support@tuflow.com. After testing we'll aim to get a 2020-01-AB update released.
  11. HI groganm and ndeeks, Yes, we are looking at a better fix for this issue. groganm are you receiving CHECK 0623, or is this stopping your simulations? We are looking at changing the file permissions when this file is created, however, on Windows this may not be possible (with Fortran). Reverting to the previous default of "C:\BMT_WBM\Log" is not preferred as creating this folder causes folder permissions for some users (which is why we changed!). If it is not possible to set the file permissions when creating the file, the next option will likely be for each user to have a folder underneath the C:\ProgramData\TUFLOW\log\ directory. E.g. C:\ProgramData\TUFLOW\log\groganm\ C:\ProgramData\TUFLOW\log\ndeeks\ C:\ProgramData\TUFLOW\log\par\ This should avoid any permissions issues. Any thoughts / issues? A couple of notes: The location "C:\ProgramData\" is not hard coded, TUFLOW uses the environment variable PROGRAMDATA. So if this has been configured differently it will use the correct path. As well as setting the Simulations Log Folder == using a command in the .tcf, this can also be set using the same command in a “TUFLOW_licence_settings.lcf” file in the same location as the TUFLOW executable. Refer to Section 11.5.1 of the TUFLOW manual for more details. Cheers Phil
  12. Hi ndeeks, The default location of this file changed for the 2020 release of TUFLOW. For the 2018 version of TUFLOW, this was being written to "C:\BMT_WBM\log\", however, not all users have write access to create files / folders in the root C:\. The default location was set to C:\ProgramData\TUFLOW\ to avoid this type of issue! The 2020 version of TUFLOW should do a check on the write permissions for this file and if the file does not have write permissions, outputting to this should be skipped. A message "CHECK 0623 - No write permission for: <filepath and name>. Skipping." should be output to the screen and .tlf in this instance. However, based on the above this is not occurring and the above error is created. If you right click on the file in Windows Explorer and select properties, in the security tab you should be able to see the permissions for the file. The location of this file can also be user defined. If you add "Simulations Log Folder == <path>" into the .tcf this will set the location. For example "Simulations Log Folder == C:\" could be used to write to the root directory (I probably wouldn't suggest this). You can also disable the writing of the "_ All TUFLOW Simulations.log" file by setting the path to "Do Not Use", e.g. "Simulations Log Folder == Do Not Use". Please get back to us if you continue to have issues with this. Regards Phil
  13. We are pleased to announce the release of TUFLOW Classic/HPC 2020-01-AA. This release was flagged as the 2019 release, but we didn’t quite make 2019, plus we thought given the amazing new features it would be a nice way to start the new year/decade. As we’ve been discussing at our various 2019 workshops, the major new features are to the HPC 2D solver along with a variety of other more general enhancements and bug fixes for both Classic and HPC. The major new features are below. For the full list of changes please refer to the release notes. Quadtree Mesh refinement Sub-Grid Sampling (SGS) of elevations for cell volume / cell face definition Mesh size insensitive turbulence (eddy viscosity) solution Non-Newtonian flow HPC AD (Advection-Dispersion) scheme The new executable and 2020-01 release notes are available for download from: https://www.tuflow.com/Downloads.aspx. This release is included in the 2019/2020 maintenance period, which was invoiced mid last year, therefore licences will need to be updated for the 2019/2020 period. For any licensing queries, please contact sales@tuflow.com. The update to the TUFLOW manual for the 2020-01 release is now underway, but in the meantime the 2018-03 release version of the manual is the latest and should be read in conjunction with the 2020-01 release notes. Happy modelling from the TUFLOW Team and enjoy these amazing new features in the HPC 2D solver. And as always, any queries, suggestions or issues, please don’t hesitate to contact support@tuflow.com.
