  1. Andy, I'd be happy to look into this. Could you tell me what type of data you are exporting (I-Data, T-Data, etc.)? Also, what revision of RockWorks are you using? This should be listed in the lower right hand corner of the program. Thanks, Alison
  2. I would suggest that you export the Shapefile through the File / Export menu, rather than through RockPlot3D. This will create a shapefile that contains actual contamination values. You can find a case study on the RockWorks support page that covers the shapefile export options in RockWorks. If you need a direct link to this (unfortunately, I can't post it on the forum), please contact me at Alison @ rockware.com.
  3. Display elevation in striplog?

    There is an option to display elevations along with depths in a 2D striplog. This “Include Elevations” option is enabled through the Depth Bar Options in the 2D Striplog Designer. You could also add a second scalebar to a 2D striplog through the Draw / Insert menu in RockPlot2D, but this would have to be added individually for each striplog. Please let us know if you have additional questions. Thanks, Alison
  4. Import a Rw3D file into datasheet Utilities

    Loann, You will need to list the names of the RW3D file in column 1 of an RWDAT file (so if you have three RW3D files, you should have three files listed in rows 1 through 3 of Column 1). You'll also need to be sure that the RW3D files are located in your current project folder. If you would like to manually select the files by double clicking on the cells in the RWDAT file, you should change the column type to a File Name. To do this, go to Column / Column Properties, and select "File Name" under Linked Data. If you continue to have problems, please send your RWDAT file and RW3D files to tech @ Rockware.com. Thanks, Alison
  5. I would recommend that you first check to confirm that the Pressure in the model is not exceeding 600 bars. You would normally get a "cannot find parameter" error in the output file for this type of problem.
  6. It is hard to know what the problem is without reviewing the model, but my guess is that the simulation is halting and outputting an incomplete time step, rather than all of the gas phase in the model disappearing. Depending on the model, it's possible that the SS value in the injection cell is actually going to 1, causing a premature halt to the model. The best way to confirm what is happening is probably to rerun the model with the print options turned on for the injection cell. This will allow you to view a detailed Cell History Plot and will hopefully reveal the problem. If you continue to have problems, feel free to send me your SIM file and I will take a look. Best Regards, Alison Alison @ rockware.com
  7. Surface geologic map

    Loann, If you want to create a stratigraphy model using the Borehole Manager, then yes, you are correct that the only way to force the model to honor geologic map contacts would be to add some additional "virtual" boreholes to the database. Depending on the complexity of the geology in the area and the number of units, you may want to consider building the surfaces that make up the stratigraphy modeling outside of the Borehole Manager (through the Utilities) using lists of xyz points. If this seems like it might be a good option, then I would suggest that you take a look at the Advanced Stratigraphy Modeling webinar posted on our YouTube channel. There are also some case studies on this topic posted on the RockWorks support page under Case Studies / Stratigraphy. If you would like to contact me via email, I would be happy to send you direct links to all of these. Best Regards, Alison Alison @ rockware.com
  8. Mineral data in TOUGHREACT

    The following publication has been recommended by one of my colleagues: Palandri, J.L. and Kharaka, Y.K. (2004) A compilation of rate parameters of water-mineral interaction kinetics for application to geochemical modeling, USGS Open File Report 2004-1068, 64 p. I don’t know how to answer your question about oxidation/reduction conditions. This might be a better question for the LBNL TOUGH2 forum, which you can find with the following Google search: LBNL TOUGH2 forum Best Regards, Alison
  9. There may be times when you want to run a TOUGH2 model from a command line. I've tried to describe the steps you would take to do this below. Single PetraSim Licenses If you are working with a single license of PetraSim you’ll need to place the PetraSim .lic file and the rlm922.dll in the same directory at the simulation executable that you need to run. We recommend that you put the input file in that directory as well. Network PetraSim Licenses You’ll need to use the floating license server to authorize the simulator use before running the model. After opening the command prompt, you can set an environment variable similar to this: c:\>set [email protected] You should substitute the correct servername and port number. After setting the environment variable, you can run the executables from the command line (below), and it will pick up and use the floating license. TOUGH2, T2VOC, TMVOC For TOUGH2, T2VOC and TMVOC, the command would look like this: Executable name <input file> output file For example, to run a model called heat_pipe.dat using EOS3, the command would look like this: eos3.exe <heat_pipe.dat> heat_pipe.out TOUGHREACT To manually run a TOUGHREACT model, you should place the following files in the directory with the executable: 1. Flow.inp 2. Chemical.inp 3. Solute.inp 4. thermodb.txt (this is a copy of the thermXu4.dat file stored under C:\Program Files (x86)\PetraSim 5) The command to run the simulation is the simply the name of the executable, for example, to run the EOS3 TOUGHREACT executable, the command would be: treact_eos3.exe TOUGH2-MP If you need to run TOUGH2-MP outside of the PetraSim software, then you should contact tech @ rockware.com for a batch file. TOUGH2-MP cannot be run from a single command.
  10. Chemical data in TOUGHREACT

    Without looking at your SIM file, it's hard to know exactly what the problem is. You should look at the bottom of the runlog and flow.out files to see if there are specific error messages. If you are getting the Singular Matrix in Chemical Solver error message, then you probably have as you suggested, an in-defined chemical system. I would recommend that you run your initial water chemistry through a modeling program such as PHREEQC or GWB before inputting it into PetraSim/TOUGHREACT, so that you are sure that you've defined an initial water chemistry in equilibrium with the minerals in the model. You are welcome to send your SIM file to Alison @ rockware.com if these suggestions do not help you resolve the problem. Best Regards, Alison
  11. Rockworks14 I-Data Profile default font

    Stuart, Unfortunately, there is no way to change the font in RockWorks14. We would expect the program to revert to a backup font, but we're not sure which one the program would use (and it may not be very pretty). You might want to consider an upgrade to RockWorks16, which allows the user to specify a different font for RockPlot2D diagrams. Also, if you do a Google search for "missing arial font on computer", you'll find some suggestions on a Microsoft forum for how to resolve the problem. Best Regards, Alison
  12. Volumetric calculation of I-Data model

    Yes, this is possible when displaying the model in RockPlot3D. If you are viewing the model as an isosurface, right click on the model in the RockPlot3D data tree (to the left of the view) and choose Options. As you adjust the iso-level, the volume of displayed material will change. If you are viewing the model using the "All Voxels" option, then you can set an upper and lower limit under the Filters option, and the program will update the volume based on the filters. Thanks, Alison
  13. How to cope with out-of-memory errors

    Unfortunately, if you are appending several models together in RockPlot3D, I think that you will eventually run into these memory errors (hopefully a future 64-bit version of RockWorks will help with this). If all of the models have the exact same extends and spacing, and if there is no overlap between stratigraphic units, then you might try the Solid / Filter / Replacement program in the Utilities to combine all of the models into a single RWMOD files (which will be much more manageable in RockPlot3D). Feel free to contact us directly with more details about this at tech @ rockware. com. Thanks, Alison
  14. I'm assuming that you are interested in the Map / Multi-log map menu item in RockWorks16. Unfortunately, this item does not have any tools for hanging the striplogs on a datum. The only way that I can think to do with would be for you to adjust the elevations in the boreholes so that the stratigraphic units of interest falls at an elevation of 0. You could then clip the boreholes in the database based on a distance away from this unit. Please feel free to send questions about this to tech @ rockware. com Best Regards, Alison
  15. Using a Civil 3D 2011 DEM file in RW15

    Mira, I opened your file up in a text editor, and it does not look like a real DEM. The first few lines of the DEM would include information about the extents and spacing of the grid. In this case, the first line is: Autodesk Export surface2DEM. Do you have an option to export a DXF Matrix? This might be a better way of going from Civil 3D to RockWorks. Best Regards, Alison Alison @ Rockware. com
  16. 3D striplogs with lithology color fill and P-data disks

    Unfortunately, there is really no way to do this unless the values in the P-Data table can be correlated to Lithology. If this is the case, then you could set up a custom color table that uses lithologic colors for various ranges of the values within the P-Data table. To use a custom color table for the P-Data fill, choose the “Based on Lookup-Table” option under the Disks/Color Options settings. I think that the feature you are looking for would be a good addition to RockWorks, so I’ll be submitting it to the programming team. Best Regards, Alison
  17. Bore hole surveys

    The Striplogs / Endpoint Comparison tool will give you the XYZ values at the bottom of each borehole. The program is really designed to compare endpoints between boreholes, so it will give you lots of other information as well. I'll add a request for a simple bottom hole xyz calculation to our wishlist. Please let me know if you have any other questions. Thanks, Alison
  18. Exceed limit of chdump calls (1000)

    Without seeing your model, its hard to know what the problem is (this error is documented on page 47 of the TOUGHREACT v1.2 Manual). You might try setting a maximum time step to see if that resolves the problem. You also might consider running the model until right before it crashes, and then restarting it with the CHDump output turned on - just in case it includes any useful information. If you continue to have problems, you are welcome to send me your SIM file, and I'll see if anything stands out to me. Best Regards, Alison alison @ rockware.com
  19. Exceed limit of chdump calls (1000)

    It sounds like you have the "Print Chemical Specificiation Output - ICHDUMP" option checked on under the Debug tab of the TOUGHREACT / Output Options menu. It states here that the simulation will end after 1000 time steps if this option is checked on. Best Regards, Alison
  20. I-Data Model problem with boundary

    Rudy, Without taking a look at your polygon and your model, its hard to know what the problem is. If the program seems to be clipping out a very this portion of the Gulf, is it possible that the cell spacing for your model is too large? Your cell spacing probably needs to be, at a minimum, 1/2 the thickness of the this thin portion within the polygon. If you continue to have problems, please feel free to back up your project through the file menu and send us an example of the problem. You can send this to tech @ rockware.com. Thanks, Alison
  21. Convergence problems

    Unfortunately, it is hard to know what the problem is without looking at your model. The output file may give you some information about the specific cell that is failing during the model run. If you can figure out which cell is the problem, you could try rerunning the model with the print options turned on for this cell to see if the time history plot gives you any more information. Feel free to send your SIM file to me - I would be happy to take a look. Best Regards, Alison Alison @ rockware.com
  22. Importing material type from ASCII files

    Ellen, This is available though the Model / Set Cell data menu. Thanks, Alison
  23. BH Strip Logs, Additional Data

    Another option would be to bring your striplog into ReportWorks and add header information there (you would have to type this in, as there is no linking to the RW database through ReportWorks). I've had other clients put together simple headers and footer in ReportWorks without a problem - just keep in mind that multi-page reports would be very challenging in ReportWorks (LogPlot would be more appropriate for anything other than pretty shallow boreholes). Thanks, Alison
  24. Flooding in Grounwater Vistas

    We would recommend that you send your model to ESI technical support. That being said, some causes of this could potentially be recharge that is too high, Kx that is too low and/or Kz that is too low.
  25. 3D borehole tubes not appearing circular

    My guess is that the problem may be caused by large XY coordinate values and small range of values, as can happen when using UTM meters for coordinates in a smaller area. The OpenGL graphics in RockPlot/3d does not have sufficient precision to show the variation on the order of 1 m when the northings are greater than 1,000,000 and the range is small. One way to resolve the problem is to subtract a number from the northing values in the project dimensions and data to reduce the number of digits and provide additional resolution. For example, use 6,300 instead of 746,300. This was reported by someone else in 2013 (forum topic 2079 titled Multi-log 3D distorted columns). If this suggestion doesn't work, then please zip up your project and send it to tech @ rockware.com. We would be happy to look into this further. Best Regards, Alison
