  1. Hi there I think the easiest way to incorporate a stratigraphic model built in AHGW into GMS is through rasters. Any practical advice on how to do this? Thanks
  2. Importing AHGW stratigraphic model

    Hi again Continued trying and managed to get the tool to run using the input shown below. However, I didn't get points with horizon elevations as I was hoping. In stead, I got the table shown at the bottom. Again, any ideas will be most appreciated.
  3. Importing AHGW stratigraphic model

    Hi Alan I guess the tool I need to use is the "Transform XS2D Lines to Points" tool. However, I failed to run it successfully. I set it up as shown below. What have I got wrong there? Thanks
  4. Importing AHGW stratigraphic model

    Thanks Alan Now I have my cross sections (2 & 3 D). How can I use them to create rasters? Thanks
  5. Hi there What's the most efficient way to export a stratigraphic model built in AHGW into GMS to be used as solids? Thanks
  6. How can one create an HK layer in AHGW from a model that uses pilot points?
  7. I've set up the correct version of AHGW with ArcGIS 10.4 but I am unable to create a world file to import a mudflow model. Any ideas or suggestions?
  8. Create MODFLOW World File tool error

    Thanks heaps Doug Gallup. This took care of the error.
  9. Model conversion problem

    I have a "neatly" calibrated (heads and flows) MODFLOW 2005 model. When I try to forward run it does not converge! I can't think of a reason for that. When I force the forward model to converge, it shows dry cells that didn't show in the parameter estimation run. However, when I use MODFLOW Newton, the result is the same from parameter estimation and forward runs. What could the reason be for the non-convergence of the MODFLOW 2005 forward run? What is the reason for differing results between the MODFLOW 2005 parameter estimation and forward run (head and dry cells)? I'll be appreciative for any thoughts.
  10. Cell re-activation

    How can one re-activate cells after being inactivated using a polygon or because they are thin cells?
  11. Cell re-activation

    Thanks Michael for your reply. This was what I did but didn't seem to work. So had to re-build the grid agian!
  12. I've been using GMS for stratigraphic modelling for a while, but I am new to AHGW. I wonder, does AHGW have the ability to determine areas where a certain layer can or cannot occur? I mean something similar to the Horizons Conceptual Model feature in GMS? I rally appreciate any advice about this.
  13. GMS's Horizons Conceptual Model feature

    Thanks Doug... I understand that you can use the clip and fill attributes to control your layers, however, I am working on a large area and something similar to the Horizons Conceptual model approach would have been easier for me to use..
  14. Coordinate systems

    I completed the tutorials with no issues at all. However, when I use real-world data things don't run well. I've got a couple of questions and I hope someone would be able to answer them: AHGW requires a projected [not geographic] projection system. Is this correct? The horizontal and vertical coordinate systems need to be compatible. Is this true? Thanks in advance for the help.
  15. Coordinate systems

    Solved === Solved === Solved === Solved === I got rid of the vertical coordinates all together and things now work 100%. Took me days to get here, but certainly worth it
  16. Coordinate systems

    I tried endless times using all possible coordinate systems, but it seems I am missing something. When I run the XS2D Wizard I get the nasty three error messages attached. Any ideas from anyone.
  17. MT3D input mass units

    Hi there... A colleague of mine has nitrogen loads in kg/ha/year and he wants to input that in MT3D as mass rather than concentration. What units should he convert his values to? Thanks
  18. Use of Specified flow=0

    The default is now flow, so you don't need to assign a BC there. If you do then it shows as wells with zero flow! I struggled with this first but then got used to it. Hope this helps
  19. When you go to open a project to add its contents into another one, the "Import into current project" is disabled (greyed) in the 7 Dec 2015 version. Is there a work around or fix?
  20. Interpolate raster to MODFLOW layer

    Downloaded the latest nightly build. Raster interpolation to RCH works fine.
  21. Interpolate raster to MODFLOW layer

    I had the same problem, so I am so glad to learn that it's been resolved. I will download the newest release and check out. I also have an image for nitrate concentrations. Is there a way to interpolate that to MT3DMS? I am thinking of a workaround where I interpolate the image into recharge then copy the recharge data to the clipboard and past in the concentration grid. But I think GMS should enable direct interpolation from raster/image to MT3DMS.
  22. I am trying to combine a stratigraphic model that has a number of aquifers with T-PROGS model. I decided to use HGUID to specify the material in the stratigraphic model and SoilID to specify the material in T-PROGS simulations. Do I have to define material for all SoilIDs and all HGUIDs? e.g. SoilIDs ====== Clay Silt Sand Gravel Peat Silty sand HGUIDs for ======== Aquifer 1 Aquifer 1 Aquifer 2 Aquifer 3 Aquifer 4 Aquifer 5 I'll be appreciative for any ideas on how to handle this situation. Thanks
  23. ModAEM boundaries

    Hi All I want to develop a ModAEM solution which has a river as its downstream boundary. The problem is that ModAEM requires the definition of a polygon for the model area in a layer where one must select "Use to define model boundary (active area). When one does this the "Sources/Sinks/BCs" option are automatically reduced and the check box for "River" disappear. Hence, it is practically impossible to use a river as a boundary for the model. Please note that I do not want to define the river as a specified head boundary. This is a problem that I have in a number of areas that I am studying and, hence, I will really be appreciative for any thoughts. Cheers
  24. GMS display problem

    I developed solids that work well on my laptop. When I transferred the files to my work computer, the material and legend did not show on the screen. Then the solids showed, but only legend text (no graphics), and then the material disappeared again. This GMS model is just behaving randomly on the work computer, which I do not have any issues with. I had the mode saved on a networks server but also transferred it to the local drive just in case. Nonetheless, I continue to have the same problem. I modified the model on the work computer where I was unable to see the solids and saved the model. Then I copied the model on a flash drive and back to the laptop, and it opened without a problem. IT here can't help and they think it's a software issue! Could anyone help please?
