  1. Thanks Michael for your reply. This was what I did but didn't seem to work. So had to re-build the grid agian!
  2. How can one re-activate cells after being inactivated using a polygon or because they are thin cells?
  3. 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..
  4. 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.
  5. 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
  6. 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.
  7. 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.
  8. 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
  9. 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
  10. 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?
  11. Downloaded the latest nightly build. Raster interpolation to RCH works fine.
  12. 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.
  13. 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
  14. 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
