Hello All, I am having difficulty in removing this Warning, have already fixed several cross sections although I now have 4 that do not seem to want to go away! The cross section 1d_xs data are all "End Cross-Sections". The cross section have 3 nodes/vertices and the centre node is snapped to the network layer see example image. Any suggestion to why I am still getting these warning or is there something simple I am missing? Thanks Fil

Thanks all, just interesting to see how the HX layers naming conventions are used. Its always strange how we modellers assume that everyone uses layers in the same way. We have seen a few models that seem to use HXi with Zpts applied and then use HX without Zpts. Maybe that's how they differentiate between applying Zpts? Although its nice to know that we are not missing something. Thanks Fil

We are currently reviewing an ESTRY/TUFLOW model and the question has come up when should a modeller be using 2d_bc_hx, or 2d_bc_hxe and 2d_bc_hxi. As on this occasion the modeller has chosen to use 2d_bc_hxi thorough out the model and now has several hundred "Check 2231" messages, we know this occurs because there are no zpt points on some of the HXi lines. So the questions we have are: When do we use these different hx types?What the benefits of each type? Thanks Fil

We have opened ~40GB XMDF files with SMS, although we do run SMS 64bit and the PC has 64GB of RAM, its not quick but does work!

Hi Both, We have not used SMS to create TUFLOW models; we currently use MapInfo and Vertical Mapper to do this. To be honest you are not really comparing like for like. ArcGIS and MapInfo are very good to create your TUFLOW model and to look at fixed time results like your final max results. Whereas SMS, we feel, is better when stepping through time steps of your model outputs and how different data can be represented e.g. Mass balance outputs, Manning grids, velocity vectors etc. We find using velocity vectors useful when understanding flows across floodplains and interaction between 1d and 2d break lines. One of the main tools we use from SMS is the creation of an AVI animation of the flood the progressing. We find this one of the most useful features as it helps to explain what is happening on the ground to non technical people. You may find it useful to look QGIS (works with shp files and is free) and the Crayfish plug which provides some of the animation tools that SMS has. Hope that helps, regards Fil

Hello,. I was wondering if it is possible to force ESTRY to run as Inlet or Outlet control? Thanks fil

Hello, maybe useful if you can look at a range also, so you can look at results in a range txxx to tyyy. Would save some hard disc space that way Regards Fil

Hi Khola, there is another way without having to alter the startup.wor file. Just add the miTools to your Tool Manger list. Go to the 'Tool' menu select 'Tool Manger'. Select 'Add Tool', give it a name like TUFLOW miTools, then browse to the location and select miTools.mbx, and then if you wish give it a description. Click the 'ok' button. If you wish the tools to load every time MapInfo opens select 'Autoload' radio button, if not you can go to Tool Manager and click 'loaded' radio button and miTools will load automatically on clicking 'ok' Hope thats useful

Hi All, think this is a limitation of IE6 Yep we still using this mordern browser! The search option will appear if the TAB key is pressed! Looking forward to having a modern browser sometime soon

Hi David, I note that you have two bridges and from the images, the water level seems close or above the soffit. Have you looked at the different approaches to modelling the bridges within HECRAS? Special ‘High Flow’ option using ‘Pressure and/or Weir’ option. You may wish to look at the low flow method as well although I do not believe that would make a difference in high flows. Also am not sure if you running the model in Steady State or Unsteady State, if the former remember HECRAS will transfer all the flow to the next cross section which will give higher values than in ESTRY or Unsteady State HECRAS runs. Also have a look at the rating curves for the cross sections in the area just to check you are getting stable results in the area. As MiTool Support suggests you may wish change the default coefficient. Page 3-20 and 3-21 of the of the HEC-RAS (V4.1) Reference Manual for more information. Hope that helps Regards Fil

Hi, we run TUFLOW 32 and 64 bit on Windows 7 64 PC. The only issue so far was when we were trying to run 4 models on the PC it would find the final licence, this seem to work later and we put it down to a memory issue. Hope that helps
