  1. SFR Package - Arc interpolation control

    With SFR the upstream and downstream elevations are specified for each segment so there is no interpolation that occurs when you use Map->MODFLOW. The STR package had the elevation at each reach so that interpolation would happen. So if you use the SFR you will have to break up your arcs.
  2. About the Font of Legend

    Unfortunately the current version of GMS does not support Chinese characters as input. This is on our TODO list.
  3. MODFLOW 6

    Yes. We have been in contact with Chris Langevin at USGS about this version and are working on supporting it in a future version of GMS.
  4. Cross Section Editor problem

    I have seen this occur on some systems. Often updating the graphics drivers fixes the problem.
  5. GMS Crash converting shape file to UGRID

    Sounds like a bug. Contact support@aquaveo.com and we will take a loot at the shape file.
  6. ETS package for Modflow-USG

    This functionality of this package will be available in MODFLOW 6. A new version of MODFLOW that will become the "new" main version of MODFLOW (like MODFLOW 2005). It has not been formally released yet but should be available in the fall of 2017.
  7. Transient river leakage

    Once you have imported the MODFLOW solution you should see a CCF item in the project explorer. Right click on the CCF item and choose the CCF->Datasets command. You should see a RIVER LEAKAGE dataset. Select the cell with the data set and then choose the Display | Plot Wizard command. Select the Active Dataset Timeseries plot and then click on Finish. You should now see a plot of river leakage for the selected cell. Right click on the plot and select View Values if you want to copy the data elsewhere.
  8. Interpretation of SEEP2D histograms

    The plot tells you information about the dataset. The histogram tells you the number of values in the data set within different ranges. I personally don't fine the histograms terribly helpful when doing a seepage problem. I look at contours and values on the mesh itself.
  9. Interpretation of SEEP2D histograms

    Can you tell us how you created these plots? What commands did you make in GMS to create them. It is not clear to me what you are looking at or trying to do.
  10. Errors in risk analysis of stochastic modeling

    I don't think there is a problem contouring datasets in GMS. My guess is that the values in the datasets that you are trying to contour do not vary much. For example, maybe there is a value of 1 at the cell where the well is and all of the other cells have a value of 0. I would create a MODPATH model for one of the wells and see how it changes when you change to the various MODFLOW outputs.
  11. Stress periods defined as dates/times

    If you have not done so already please contact support@aquaveo.com to look at your project.
  12. Errors in risk analysis of stochastic modeling

    You can create parameters from the values of HK assigned to the materials. Then use the parameters dialog for these HK parameters just as you did the RCH parameters.
  13. Errors in risk analysis of stochastic modeling

    Those are dataset that you should be able to contour. If something is still not working you should contact support@aquaveo.com.
  14. Kriging with logarithmic semivariogram

    From looking at the code it looks like the warning means that there is something wrong with the input lag parameters and that the kriging code could not find points to create the variogram. As to your second question... The experimental variograms are used as a guide to create a model variogram. This is the variogram used to do the interpolation. I am guessing that your model variograms would be quite different if compared logarithmic to non-logarithmic.
  15. GMS Solids to Modflow, HUF, and K

    The solids to MODFLOW command will create the HK data for the LPF package. The HK array can then be contoured. Currently, there are no tools in GMS for creating a dataset of HK values from the HUF package. If your HUF data was created from solids, you could use the Solids->MODFLOW command to generate an HK array with the LPF package so that you could visuallize the HK data.
