  1. Yes, clearly all your modelled heads are all overestimated. Obvious quick fixes to try would include increasing K and/or lowering recharge. Try playing with PEST ranges.
  2. Time-axis label format setting

    Hi Cody I am using ArcGIS 10.4 Thanks
  3. Hi all Playing with the time series tutorial, I am unable to get the time-axis labels to plot correctly. I get years like 1899, 1900, 1901, etc. The time series table is fine though. Any ideas/suggestions? Thanks
  4. Dear isiarkos I would say you'd better include a "recharge code" field in your shapefile and use it to group polygons for recharge value assignment. Or, you can assign recharge values to the shapefile so that recharge values will be transferred to feature objects when you process your shapefile in GMS. This way, keeping multi-part features is not needed. I hope this helps
  5. Your shapefile polygons may also be intersecting each other. Check them in GIS first and correct topological errors.
  6. 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.
  7. 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
  8. Importing AHGW stratigraphic model

    Thanks Alan Now I have my cross sections (2 & 3 D). How can I use them to create rasters? Thanks
  9. Hi there What's the most efficient way to export a stratigraphic model built in AHGW into GMS to be used as solids? Thanks
  10. 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
  11. How can one create an HK layer in AHGW from a model that uses pilot points?
  12. Create MODFLOW World File tool error

    Thanks heaps Doug Gallup. This took care of the error.
  13. 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.
  14. 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?
  15. 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!
