  2. The 3 sides with rock don't need anything. The 4th side needs some condition to allow water to leave (or enter), such as a constant or general head boundary...river/stream, etc.
  3. Hi, This morning I tried to register GMS with my teacher, but since I'm using a MacBook with virtual machine it does not work properly. Any advice or tips on how to make it work? Thanks in advance
  4. Forum friends, Could anyone possibly enlighten me on why in some of the elements i am registering a velocity but in those same elements there is no water depth? Shouldn't they be equal?

  6. Sir i have flow model covered with solid rocks on three side and 4th side is continous . How i define boundary conditions . It has assumed that water can not enter or leave the system in rock covered 3 sides. Pl help
  7. Hi everybody I am new to SMS-TUFLOW. I am having some problems with the model as every time when I delete or modify the boundary of the model, the model become unstable. For example, in this model, it ran smoothly before. But when I added two more polygon in the material, when I run it, the error pop up and said the Tuflow model is unstable. I checked the error message and it said "Negative V depth" "Negative U" . I have the feeling I need to do some extra steps when I want to modify the boundary because when I rebuilt the model again with the extra polygon, it ran smoothly. Could some one advice me how to fix this problem because I cannot just rebuilt the whole model when I want to modify something. Thank you for your time
  8. Hi, I am a new user of SMS for SRH2D. I converted my CAD surface to a landxml format and brought it into SMS as a scatter set. I right clicked on the scatter set and converted Scatter->2D Mesh. I created a boundary conditions and materials coverage. I setup a new SRH2D simulation but was unable to drag the mesh into it. When I hit run, it says the mesh is unstructured. Can someone please tell me what I am doing incorrectly. Further everytime I hit save I get an error, snapshot is shown below. Any help would be appreciated! Thanks,
  9. Hello. Has somebody worked on ship-induced waves modelling with Bouss2D?
  10. I am building an existing conditions model for a short river reach. My simulation includes the existing Mesh, Materials Coverage, and Boundary Conditions Coverage. Prior to running, I completed the "model check" option with no checks violated. When I proceed to run the simulation, I receive the error below. I tried re-making my mesh, thinking maybe it didn't get saved in the files properly, however I still receive the same error. Is anyone familiar with what the srhgeom file may be referring to or why I am missing it? Program stopped due to the following: specified srhgeom file does not exist Error Code is: 1
  11. Possible solution: Create a field associated with DRT for "Return Feature". This would be a text field and the user enter the "name" of the associated feature. The user would need to be sure that the "name" was exactly the same on the associated point, arc, or polygon. Out of curiosity, could you tell me about the applications where you are using DRT? What is the real system that you are modeling? I am interested in knowing how the package is being applied.
  12. I will be a very helpful feature enhancement when using the DRT-Package to be able to select the Return-Points, Return-Arcs or Return-Polygons in the Map Coverage. At the moment one has to do that Cell based in the Modflow Menu and repeat this again everytime something is changed and mapped at the DRT-Coverage
  13. Hi. I would like to know if it is possible to model ship-induced waves with Bouss 2D. In case the software does it, I thank you in advance if you share information or guides to work with.
  14. Hi: I have a MODFLOW project that I am creating with GMS for a class at UCLA, and I need to convert it to be read into the MODELMUSE software so I can submit my assignment and the TA can grade it. Does anyone know how to convert a GMS MODFLOW into MODELMUSE MODFLOW? Steve Turnbull cell 808-295-4998
  15. It happens since GMS 10.4.6, both on me and my colleague. We were working on a huge project and sometimes the software just crash when it updates the display or saving. Sometimes crashing wouldn't hurt anything we can easily restart the software But sometimes after crashing the software can't be launched. If you check with the Task manager, you could see when you open the software, the process shows in the task manager for several seconds and then disappears. We've tried to repair the software by the installation file, reinstall the software, even removing the registry form, but none of them helps. The only solution is to reinstall the operating system. ( currently we use windows 10, it previously happened in Win 7 also) Anyone encountered the same problem? Any solution that easier than removing the whole operating system. Any input would be appreciated. Thanks in advance.
  16. Thanks @heimo! So the information regarding E6T elements on the SMS wiki is indeed incorrect (refer to my first entry in this thread). Hopefully this will be updated. Thanks again!
  17. Tough to describe here, but I'll try to do it briefly. You actually have to set it up to have 2 values for the same time. The first value would be zero and then second will be one. Then when you want to end having it be one, you make another entry for that same time and make it zero. It ensures that there is no averaging from one time step to the next.
  18. Hi All, I have created a few drain coverages, when I map these coverages to MODFLOW, one stress period before that defined in the original coverage becomes active as a drain. For example, in the screenshot below in the coverage I define the beginning of drainage at timestep 61 (as indicated by a conductance value of 1). However, when examining sink/sources for cells defined as a drain using that coverage, the timestep prior to the one defined in the coverage becomes active and is given a conductance value ~ half of that given to other stress periods as shown in figure below: The final drainage timestep in the coverage is correctly defined as the final drainage timestep once mapped, however it too is given a conductance value ~half of that given in the interim stress periods. Could someone please advise what is happening here, and whether it is possible to have a consistent conductance value assigned to the timesteps originally defined in the coverage?
  19. Hi! I tested you file and it opened in SMS 9.0. I also created following test file. Both nodes and elements are loaded and shown correctly. May be a SMS version problem. Testgrid.2dm
  20. Hi everybody, i want to import an old model created by PMWIN to GMS. The import of the modflow simulation was no probem. But has anybody an idea how to import the MT3DMS simulation in GMS? Best regards
  21. Anyone? Please let me know if I can clarify the question or provide any additional information.
  22. Hi, I have the same problem. My MODFLOW-USG model is running with certain horizontal and vertical hydraulic conductivity values. However, if I changed the horizontal and vertical K, the model wont converge as a results of dry cells. I am using '(1) Newton with Delta-Bar-Delta' with layer types of 'Convertible' in the LPF Package options (the model wont converge by selecting the 'Convertible Upstream' option). I also using the latest version of MODFLOW. Any advice is greatly appreciated.
  23. Hi I need to calculate the salt/mass load (salt/mass load contribution of the groundwater contaminant plume to the stream/drain) in certain streams from my MT3DMS model. What is the best/easiest way to calculate it? My input units are in metres and mg/l. Do I select compute mass flux at sources/sinks in the Transport observation package menu? Then use the drain coverage to see what the mass flux is along the segment? What unit is this mass flux then in? mg/day ? mg per time step?
  24. Hi Pierre, Did you ever find a workable solution or relevant literature for this problem? I'm having the same problem with a regional alluvial aquifer model.
  25. I think you may be right about the XML not necessarily making a good mesh. I'm having success bringing in some breaklines from Civil 3D into the mesh converage for the roadway, then generating the mesh using the XML Scatter. As long as the breakines are not too close together I'm finding. I'm getting good road crown definition and contouring now. Thanks!
  26. I'm creating a fairly simple SRH-2D model simulation with a small inflow hydrograph and Exit-normal flow for boundary conditions. I am right-clicking on the Scatter that came from the XML and Convert>Scatter->2D Mesh. Then I don't have an option to link that mesh to the simulation... Only meshes created from mesh generation coverages have I been able to link to simulations.
