  2. It is my understanding that the diffusion coefficient for all aqueous species is assumed to the be the same in TOUGHREACT. You might contact the TOUGHREACT authors at LBL to see if they have any ideas or planned developments on how to deal with this limitation.
  3. As far as I know, only one solute diffusion coefficient can be set for the whole model,which is not practical. Then how to set the diffusion coefficient of different solutes in different soil layer in toughreact?

  5. Hi Msmisitel, I suggest plotting the XYZ points with the RockWorks 2020 with the Utilities 3D | Points menu command. Use the G value in the Style | Advanced | Size & Color | Color | Proportional menu to set the color of the point proportional to the G value. A gridded surface created with triangulation or other methods probably won't work because it requires a single Z value at each XY location. You may be able to grid the top and bottom of the tunnel separately if you can split the data set. Regards, Tom B RockWare Inc
  6. Hello, I have question. Is there some option to import tunnel shape as a point cloud to project? I use Rockworks 20 for my project. I have large pointcloud of tunnel with parameters X,Y,Z,G = deformation. I want to get informations about deformation to project with shape of the tunnel. I thought that I can use triangulation surface, LIDAR - triangle mesh, or LIDAR ASCII grid, but i seems that isn't correct way. Could somebody help me?
  7. Hi Tom, i tried it and it helped me a lot. Thanks for the quick reply !.
  8. Hi Nicooh, Here are a few general tips to help resolve the problem. For more specific advice, backup your project with the File | Backup Database menu and send us the ZIP file. Check your boreholes to make sure you have formations listed down to the total depth of the borehole. Use the Strat Picker in the Striplogs menu to add missing formations. Increase the grid cell spacing in the project dimensions for a higher resolution grid. Turn on the option for High Fidelity to make sure your Stratigraphy model honors your data. Turn off the options for Smoothing and Declustering. Change the gridding algorithm to a different method, such as Inverse Distance or Kriging. You may even want to try the Triangulation method. Support for RockWorks 16 will be ending in the next few months. Be sure to upgrade to the current version (RockWorks 2020 at the time of writing this message) for the best discounts. Regards, Tom B RockWare Inc
  9. Hi all, I am working on a project and i had problem modeling some section on RW 16, i could not solve it. I need the model reach to the maximum depth of each borehole, because i am modeling a geographic fault, however i get this (attached ). I am using the inverse distance on the gridding options. I hope someone can help me, thank you. PS: sorry for my bad english, i am workin on it.
  10. Did you know that you can use optional fields in the RockWorks Borehole Manager Database, along with SQL statements, to easily enable groups of boreholes within a project? Check our RockWare's latest blog post - Using Optional Fields and Playlists to Enabled Borehole Groups in RockWorks 2020. Molly RockWare Inc.

  12. It builds the model first and then truncates it, so I don't anticipate you having any problems with the collar elevations not matching the DEM.
  13. I am thinking that it will work better with a smaller number of higher quality points, and including structural data with them. If I put in points along a contact, and constrain the model with the ground surface, will I run into problems if there are small differences in the collar elevation and interpolated ground surface? I m worried that the model might truncate the interval of the borehole that includes the contact, and therefore not see the contact. Or does it build the model first and then clip to the ground surface?
  14. My guess is that tens of thousands of points would be overkill. I would start with a smaller dataset and build up from that. Maybe increase the number of points to 8000 to see how it works first?
  15. I have just run a test with a handful of contacts converted to points/psuedo boreholes, which added about 800 points. Am I going to run into problems if I end up adding tens of thousand such points?
  16. Also, there are fields for strike and dip in the Stratigraphy table. Use the Tab Manager tool to enable the fields. If you populate these fields, then you would want to use the Dip interpolation algorithm during model creation: Unfortunately, other interpolation algorithms don't take strike/dip into account, so you really just need to experiment to see if this approach works for you. Limiting the number of points or applying a cutoff distance seems to help create more realistic surfaces.
  17. You will definitely need to resample the DEM or LIDAR surface to match your project dimensions. This can be done through the Grid|Math|Resample program under the Utilities. In most cases, you can import the DEM as an ArcASCII file (or some other format), but you may not be able to display it. You just need the RwGrd file to be created so that the resample tool can be used to bring it down to a resolution more appropriate for geologic modeling.
  18. Thanks. I am using Rockworks for the first time, and really appreciate the advice. I am making a fairly detailed and accurate geologic map on a lidar base, so I will have plenty of contacts on multiple horizons to include. I assume there is no way to include strike and dip data directly. I was planning on using the lidar as a topographic surface, but Rockworks choked on a 600,000 cell USGS DEM so I can't imagine how it would handle 1m lidar.
  19. I think this is a good approach. Depending on whether you need to model other units as well, you may want to add additional contacts to the database, both above and below ground (perhaps using an average thickness value for each unit). When creating the Stratigraphy model, be sure to use a "Constraining Surface" such as a DEM or grid that is based on borehole elevations. Feel free to send us your project if you are having a problem creating a model that reflects these superficial contacts. Best Regards, Alison
  20. I wanted to add a couple of additional suggestions. 1. An easy way to populate an optional field is to use the File | Locations -> Datasheet tool to transfer data in the Location table of the Borehole Manager Database to the Datasheet. You would want to do this AFTER adding the optional field to the database. You can then populate the optional field, possibly by copying and pasting, and then you can transfer the data back to the Database through the File | Transfer | Locations-> Borehole Manager tool. 2. You might consider creating a playlist that gives you tools for turning on and off groups of boreholes based on SQL Statements. I would recommend that you include one SQL statement that disables all of the boreholes in the database, and you can then include additional items that enable various groups of boreholes based on optional field data. You can check on only the statements you want to use depending on the group of boreholes you want to enable. Here are some examples of SQL statements: a. This statement will disable all of the boreholes UPDATE [Location] SET Enabled = 0 b. This statement would enable only the boreholes with an "x" in an optional field called "HPT" UPDATE [Location] SET Enabled = 1 WHERE ("Location"."HPT" = 'x') c. This statement would enabled only the boreholes with aExample SQL Statements.RwPlaylistn "x" in an optional field called "MIP" UPDATE [Location] SET Enabled = 1 WHERE ("Location"."Mip" = 'x') Obviously, these SQL statements will vary depending on the way you've set up the optional fields. To turn on the MIP boreholes, you would check on just the first and last statement (not the HPT statement), and then run the Playlist. I've attached a playlist with these three items so that you can download it and experiment a bit.
  21. I am trying to combine borehole stratigraphic data with geologic map data. From what I have been able to gather, this is done by creating psuedo boreholes at locations where the map provides stratigraphic data. To convert my contacts, I first converted the polylines to vertex points, then gave each point a collar elevation equal to the ground surface elevation, and then added two stratigraphic intervals. One interval extends from -10 ft to 0 and has the overlying unit, the other goes from 0 to 10 ft and has the underlying unit. Is this the right approach? Is there a simpler way to do it?
  22. Thanks, that did the trick. Tedious to go through and populate the optional field but now I can easily sort.
  23. There are a few ways to group boreholes. One is to add an optional field, then Filter/Select to update the Enabled flag based on the values in that new field. Another is to create a list of borehole names either by just typing them into a text file or from the Edit menu "Save Enabled/Disabled borehole list", then use "Enabled/Disabled boreholes Based on list" from the same menu to update the Enabled flag when you want to switch. If the boreholes are geographically differentiated you can create a sub-site (which sounds like it would not work for what you need).
  24. Is there a way to group boreholes in borehole manager so that you can view subsets of data without having to check and uncheck dozens of boxes in the borehole list. For Example, I have boreholes that include bedrock scattered among many that do not, and I would like to look at the two datasets separately. There are hundreds of boreholes, so toggling between sets by unchecking individual boreholes would be tedious.
  25. Gridded surfaces can include use strike and dip information when you create the grid. Choose the ModOps Grid | Create | XYZ & Dips -> Grid menu. Sold models require XY location, Z elevation (ground minus depth), and G (a unique numeric ID) of each node within the item. Regards, Tom B RockWare Inc
  26. Hello everyone, I am very, very happy to be part of this Forum. I am a student in Mining Geology, option Applied Geophysics. I developed a 2D geological model from geological field observations and geophysics (Magnetism and Gravimetrics associated). Since my 2D model is already realized and that I can evaluate through geophysics the depth of the bodies and geological structures constituting the 2D model, how to do or what approach I should use to reconstruct this same model in 3D please. Thank you in advance for your attention.
  27. The Midas.dll error can occur when RockWorks20xx is launched. It is caused by the midas.dll file not being properly registered. To correct that follow the steps below. Close RockWorks. Open up a command prompt by selecting the windows button + R at the same time. Type cmd into the Run window like the screenshot below which will bring up the command prompt window. On the first line after C:\Users\Username type (or copy and paste) in: cd "c:\program files\rockware\rockworks20\" and hit Enter. That should bring up a second command line starting with c:\Program Files\Rockware\Rockworks20\ and after that type (or copy and paste) in: regsvr32 midas.dll and hit Enter. A window should then pop up saying: DllRegisterServer in midas.dll succeeded. Below is a screenshot of what this should roughly look like. If the error persists, users have found that running a registry cleaner solves the problem, presumably by removing conflicting references to the DLL. Molly Mayfield RockWare Inc

    Hi Allison, Thanks for your posting.A few questions: Can you specify the revision of RockWorks you are using (e.g. 2020.9.3)? I'm having difficulty recreating this issue in both RockWorks17 (the last posted 2020.5.6) and RockWorks2020 (the current 2020.5.3 build). Does the output file look different if you open it into a different program? Metafiles are tricky because they can look very different when opened into Paint, for example, versus Word or Illustrator or PaintShop or... Do you need to use the EMF/WMF for your desired output? High-res raster output is more predictable. You are welcome to email your RockPlot2D file (.Rw2D) to support at rockware.com and, with the information from above, we can try to recreate the issue. Thanks Molly Mayfield RockWare Support
