  1. I have a model that was created in Vistas which I'm attempting to convert over to GMS. Note that the original model did not include nested grids, so the node number should be the cell number. Anyways, I have the grid set up and was able to get the recharge in. However, the source/sink files (drn, riv, str, etc.) use nodes. I attempted to drop the information into the MODFLOW files, but I get the error that it wants to look to the HDF5 file for the data. How can I get around that? I put in a test drain, saved the file (the data apparently went to the h5 file)....but when I tried to comment out the reference to the h5 file and attempted to add/read in a couple more drains in the MODFLOW file, the model still pulled in the data from the h5 file. I thought that was a bit odd. Anyways, I have all of these node-based points which I should be able to read in, but can't figure out the best way to do it. Any thoughts?
  2. Just as a follow up based on your concern, the "thin upper layer" can be as thick as you want it to be to avoid that issue you mention. You can design your layers to meet your needs. Could take a little time, but shouldn't be too bad. Try sketching it out on paper first to visualize how to do it. First the way it currently looks, then with new layer divisions and material properties. Just a little imagination and it will work.....
  3. Can you make the extension of the thin Layer 1 basically the same material/properties as Layer 2 such that you don't have to inactivate it. For example, make your outcrop Layer 2 one foot thinner, and extend Layer 1 in that area (one foot thick)....then make all properties the same as Layer 2 (need to make sure that your vertical properties work such that flow doesn't get held up at the boundary between layers). Just a thought.
  4. Well, unless things have changed (I haven't done this in a while), it doesn't matter if your well is screened in the middle of a layer/cell. For MODFLOW, the well is assumed to be across the entire cell. However, you can release particles in the middle of the cell to better simulate things....although it won't be that accurate inside the cell. So you can release particles in the cells in the two layers by selecting those two cells and manually placing particles at certain locations in the cell. I don't know if you can do much more than that.
  5. Select the cell(s) with the well(s) and you will be able to generate particles and tell it the tracking direction.
  6. I do recall that by loading/running GMS on a different computer, the issue was resolved for me (I think it was a newer computer which had the font that the program was looking for). If it can't find the font it needs, I think it just grabbed WingDings (which is why you get symbols instead of letters). I'm pretty sure that they took care of the issue in the later versions, so I'm not sure if you will get this resolved. Now, you seem to have a newer system, so I'm not sure if anything can be done besides you just upgrading to a newer version.
  7. This is an old font library issue. Off the top of my head, I don't recall the fix, but if no one else chimes in, I'll look into it a bit more to see how it was resolved.
  8. Sorry - I think the developers may have to look at your files. The only thing I can come up with is that you are trying to map to some cells which aren't active for transport, thereby causing an error/crash.
  9. Okay - for your Conceptual Model, right mouse click on it and go to properties. I'm sure you already clicked on transport being included, but you also need to click the button for define species and than add a new species. I just did that and the recharge concentration came up for my polygon.
  10. Have you actually initiated a MT3D model? I suspect that option will be available once you do that.
  11. From your 3D grid, you need to create a 2D grid so that you are only working with one layer in the calculator. Once the 2D grid is created, when you go into your Top elevation, you can now generate a 2D data set. That is what you use in the calculator. After you subtract the barrier depth, you will have a new 2D data set. Use that as the top elevation of Layer 2 (or bottom of Layer 1). You can just hide the 2D grid in the background - it won't impact any of your modeling.
  12. One thought: If you already had your ground surface set in the first model, why don't you use those elevations in the data calculator and subtract the depth of the barrier from that data set which makes the top layer the same consistent thickness and you don't have inactive cells (unless they are dry)? That might help.
  13. Oh - I like that one! Still not a fantastic solution, but one that shouldn't require too much effort! Thanks!
  14. Thanks - If others think that a way to output this information would also be useful to them, please chime in. I would add it to the feature requests forum if it is more than just me and a co-worker who wants this.
  15. I was asked this question by someone and figured it would be good to see what others have done. There is a MODFLOW grid with variable cell sizes. The person would like to perform calculations which require use of the individual cell areas. Is there any way to export the information on cell area to a spreadsheet such that the array is arranged similar to the grid? Right now, we can open up arrays for specific parameters in GMS like recharge, copy and paste the info into a spreadsheet, and work with the data that way. It doesn't appear to be possible with cell dimensions/ areas. I can certainly open up the MODFLOW text files, pull the cell dimension info into Excel, and run a macro to arrange the array, followed by a calculation of cell area, but I would love to know if there is an easier way. Thanks!
