  1. MT3DMS Plume Center of Mass

    There is not a tool in GMS that does this. Out of curiosity, what is your definition of the center of mass of a plume?
  2. Array-based parameters with clusters and instances

    This tutorial covers parameter clusters and instances: http://gmstutorials-10.3.aquaveo.com/MODFLOW-AdvancedParameterOptions.pdf Be aware that parameters with clusters and instances are usually more difficult to work with than parameters specified with "key values."
  3. The output control dialog is specific to the MODFLOW output control package. The items that you mention are not part of the MODFLOW package. However, you can compute each of the items that you have listed using the data set calculator.
  4. Speedy When you run PEST on the computer with the problem can you see if another program is running: tail.exe? This program is used to see the text being written to the pest output file. I am assuming that there is something wrong with that program on your computer. I am not 100% percent sure this is the problem but it is worth checking.
  5. Index is out of range

    Are you using the latest version of GMS? If not, try that first. If you are, then it is possible that there is a bug and you should contact support.
  6. Transient spatially distributed recharge

    We will be adding a feature to the next version of GMS to apply rasters to various stress periods in the Areal packages (RCH, EVT, ETS). There will not be a need to import these into your project they can be processed directly from the RCH package.
  7. MT3DMS Error with MODFLOW-NWT

    SEAWAT is based on MODFLOW 2000, not NWT. That may cause you problems. Also, if you use MODFLOW-NWT and your model includes SFR, LAK, or UZF then MODFLOW will write an HFF file that is in a format the MT3DMS does not recognize and you will have to use MT3D-USGS.
  8. LPF package

    It is difficult to answer this question without seeing your model. I don't know of any reported bugs with this feature so you may have missed a step. If you need further help feel free to contact support.
  9. Well screens

    The sign on the flow rate for extraction with MODFLOW is negative and positive for injection. Check that you have the extraction specified with a negative value.
  10. Observation points using MODFLOW USG

    No limited number of observation points. From the description it would be difficult to trouble shoot your issue. You should contact support@aquaveo.com for some help.
  11. MT3DMS

    Go to the Starting concentrations dialog from the MT3D basic package. Then use the "3D Dataset -> Grid" button to map the dataset that you created with the interpolation tools to the starting concentrations for MT3D.
  12. Observations in MODFLOW-USG

    They work differently in USG because there is no OBS package. See this tutorial for more info: http://gmstutorials-10.3.aquaveo.com/MODFLOW-USG-Calibration.pdf
  13. transient recharge

    This looks like a bug. Can you contact support@aquaveo.com so we can look at your project and fix the issue.
  14. Fixed pilot points in PEST NSMC

    Do you know what the error condition is that prevents PAR2SEN from working?
  15. Fixed pilot points in PEST NSMC

    So the tutorial seems to work fine with fixed points. I just tried it again this morning. Does PEST report any errors? Perhaps it is a bug in parallel PEST.
