  1. Importing ESRI Shapefiles into RockPlot2D

    What type of shapefile are you trying to import (points, lines, polylines, etc.)? Regarding the coordinate system, RockWorks does not do any conversion during this import. You should make sure that the shapefile is in the same coordinate system and units as your project. You may need to reproject the shapefile and re-export it from GIS before importing it into RockWorks. If you continue to have problems, please send the shapefile and a description of the problem to tech @ rockware.com.
  2. Export to MODFLOW

    Yes, this is available under the Grid|Filters|Polygon tool. You'll need to create a polygon table that contains the xy locations for the vertices in the polygon.
  3. Export to MODFLOW

    When you create a stratigraphy model, top and base RWGRD files are created and stored in your project directory. They are named based on the names of the stratigraphic units in the project. To export one of these RWGRD files as an ASCII file, to go the Grid|Export menu in the Utilities portion of the RockWorks program. There, you'll find the option to export both ASCII file and Surfer GRD files, which would probably work as well in Visual MODFLOW Flex. I hope this helps!
  4. Export to MODFLOW

    How you approach this probably depends on which MODLFOW interface you are using. I think in most cases, the ASCII XYZ export (through the Grid menu) will likely load as a surface into your MODFLOW interface. I would probably turn off the header, and you can adjust the delimiter based on your preference (tab, comma, space, etc.). Also, if you are using Groundwater Vistas v7 and RockWorks17, we have added some new tools for exporting grids in a format that can be automatically loaded into Groundwater Vistas. You can find more information about this by doing a search for Groundwater Vistas in our Help files.
  5. Effective or Total Porosity in TOUGH2 EOS1

    Jared, I believe that you would want to use effective porosity, but am really not sure about this one. I would recommend that you submit this on the TOUGH forum hosted by LBL. The TOUGH authors are definitely the most qualified people to answer this question. Thanks, Alison
  6. Valentina, Well plots are used to plot mass accumulation in the cells that intersect a well. So, if wells are inactive, you will not be able to view well plots in a SIM file. There was a known bug in PetraSim v2017 where non-interpolated line plots (cell-based plots) were not plotting correctly, so this is likely what you are encountering. This has been resolved in PetraSim v2018. If you continue to have problems or have specific questions about your license status, feel free to contact me at alison @ rockware.com. Best Regards, Alison
  7. Unable to make fence diagram

    It appears that you need to add vertical exaggeration to the striplog (and most likely any sections or fence diagrams you create). To do this, adjust the Intended Vertical Exaggeration Factor to something larger than one (I would suggest 10 to start with), and then click the Process button to re-create the strip log. If you continue to have problems, it would probably be best for you to send us your project, which includes the database and your current menu settings. You can do this by Backing up the Database through the File menu, and sending us the zip file created during the backup process. You can send this to tech @ rockware.com Best Regards, Alison
  8. Export to MODFLOW

    Dear Rudyabo, Thank you for your input, we are currently working on some tools that will allow both RockWorks RwGrd files and block models (representing lithology, permeability, etc) to be imported into the Groundwater Vistas MODFLOW interface. If you are interested in learning more about these, feel free to contact me and I will send you additional information (we are currently working on a case study covering these tools). Best Regards, Alison Alison @ RockWare.com
  9. Exporting 3D solid model voxel information

    Msayed, Because RockWorks uses constant spacing in each direction, the connection areas and distances are going to be constant in each direction. Regarding corners, you could shift the cell centers over 1/2 a cell distance in each direction to get a list of cell corners (you would also have to add corners along three boundaries of the model. We do not have a specific export written that includes this information. If you want to provide a format that is a standard for import into an FEM model, our programmers can take a look to see how hard it would be to reproduce. Please send this type of information, along with your contact details and license information, to tech @ rockware. com. Best Regards, Alison
  10. Hello Alison,

    I have question about importing the CPT data from Excel to Rockware. I have been trying and looking to the videos on  YouTube, but still have problem. 

    I will upload the Excel file that I'm trying to upload. 

     

    Thank you much in advance

  11. Wellbore-Reservoir Coupled

    The pressure represents the flowing bottom hole pressure described by the TOUGH2 manual (introduced on page 64). PetraSim includes a Start-up time option that is not available in the standard version of TOUGH2. You may be able to create multiple wells that fall into the same cells that start up at different times (presumably, the pressure in the producing wells would decrease with time, so you would start up new wells with lower flowing bottom hole pressures at later times in the model). You could also restart your model at the times where you need the pressure to change or for certain wells to be disabled (which is probably how people using the standard version of TOUGH2 handle this).
  12. Manage completion history of a wellbore

    Hi Julia, My suggestions would be to either: 1. Store date information in the Caption field 2. Add a custom field to the Well Construction table to store date information Unfortunately, neither of these fields can be queried during plotting, but you would at least have a way to identify when each item in the well table was in place. Maybe other users will have some suggestions as well. Best Regards, Alison
  13. I agree that it is strange that changing the output settings would affect the simulation run. I think its possible that adding specific print times would do this, as it changes the time steps required by the simulation. Changing the number of time steps output shouldn't change the simulation. I would be happy to take a look at your simulation and see if I can determine what is going on. Please send your SIM file to Alison @ rockware.com. You also might want to post this question on the TOUGH2/T2VOC forum supported by LBNL, as the TOUGH2 authors are really the most qualified to answer questions like this. Best Regards, Alison
  14. These parameters are described in the TOUGHREACT manual starting on page 31. CGUESS: initial guess for the concentration of the individual primary species (not total concentration), in moles/kg H2O (molal) for species other than H2O and in kg for H2O. Input values of CGUESS do not affect results of speciation calculations, but could affect the number of chemical iterations required during initial speciation computations. CTOT: if ICON=1, CTOT is total moles of aqueous species, and total amount (in kg) of liquid water for H2O. Molalities are then internally computed as CTOT/CTOT(h2o). If ICON > 1, refer to the discussion of ICON above for the meaning of CTOT.
  15. The mass fraction is based on units of mass (so grams of salt per grams of water).
