  1. Hi Sakura, I didn't get a chance to read the forum in a while. Sean has given you all the correct advice. You are in good hands. In summary, I would try running the model and would not worry about the warning at this stage.

  4. Hi Sarath, My understanding about your actual condition is limited. With the understanding I grabed from your text, a simple rectilinear modflow model will do this. Diaphragm walls can be represented using a barrier with appropriate HC, (https://www.xmswiki.com/wiki/GMS:HFB_Package). I would start with single 2 layer model (1 above the excavation level and other one below that level). Best regards, Lalith

  6. Hi, Why are your horizons so much off from the solids? Where is your grid? is it completely inside your solids? Can you make only the solid edges and remove the solid faces and also add the grid with a different specified color. I would like to see both the grid and solids frames in the same figure. best, Lalith
  7. Please make the boundaries that are used to create solids little bit larger than the boundaries used to make the modflow grid so that solids would cover the grid sufficiently (make a buffer). Sometimes, grid cells are created that crosses out the boundaries (when using specified heads for example). If the same boundaries are used to create solids, then those solids do not cover these boundary cells and provide this error.

  9. Please assign two coverages in your conceptual model. One for each set of layers that requires unique GH at the boundary. Assign "layer range" and head properties appropriately as shown below. Please also assign "Default Layer Range" at the bottom in each coverage as you need. For example, one general head boundary condition for the layers 2 to 5 can be assigned in the set up below. Multiple coverages like can be set up in the conceptual model as necessary.
  10. Than you Bri. That works. Wonderful solution.
  11. Hi, I have a working Modflow-NWT steady state model. However, it does not trace capture zones using modpath. Error message states as: " RUN STOPPED because cell thickness is negative" Does modpath work with Modflow-NWT? Any help is appreciated. Thank you, Lalith
  12. Probably, I am not understanding your question properly. This is my understanding based on my limited experience in USG and I can be wrong. You can't copy and paste material type in USG because layers are not retired to be continuous. In USG, assigning the material type to the grid is a part of Horizons -> Modflow mapping. You might need to make sure your boreholes and horizons match your material type requirement and map it. I think you need to contact Aquaveo for a definite answer.
  13. As far I know solids can't be mapped to UGrids. You need to directly map the boreholes with horizons, cross sections, TIN and Raster Catalogs to Ugrids using "Horizons -> UGrid ". Did you assign Horizons to boreholes before you start this mapping?
  14. It worked for me for a huge data set. Probably you might want to experiment a little bit. I would delete few data sets at a time and check. Then, you can find what drives to the error. Good luck
  15. Update about this situation. Aquaveo technical assistance confirmed that SEAWAT in GMS is compatible only for modflow2000. In modflow-NWT and modflow2005 there is a package for saline intrusion (SWI2 under additional packages) but its more 2D and is not as sophisticated as SEAWAT.
