  1. Helo, it is hard to say without seeing the model. Could you be more specific in what do you mean by "nothing happens"? Do you mean like, the tracer concentration is zero everywhere through the simulation? First look at the mt3dms list file (case.out) and make sure, that the simulation ended without any errors. Then I would suggest to look at Output control in the basic transport package and make sure it is set properly, so MT3d is writing the concentration binary arrays at correct times. Also try to look at the model cell containing the injection well via sources/sinks dialog and check, that there is associated concentration with it.
  2. There should be no obstacles in inactivating inner area of a single layer model using IBOUND. See the attached image.
  3. Is each head observation in the *.hob file maped to the unique cell (IJK) and stress period? Athought it shouldn't matter if the observation's coordinates/times are not identical due to the offset variables (TOFFSET, ROF, COF), I can imagine certain confusion if multiple observation are defined for the same cell and stress period when using PEST.
  4. Hi It would be a nice feature to be able to display piezometric water level of a specifed layer(s) in a cross sectional view (row or column view) in adition to the free water table already implemented. I guess it would be suffictient to add one additinal curve to display and an option to specify from which layer the heads should be extracted. Clipping of the contours could remain as it is - using water table if water table is switched On or the second curve if water table is Off. Thx Michal
  5. Hi speedy, it seems you need to enable the MT3DMS SSM package to enable the mixing of fluid coming from the constant conc. BCs. I would try to enable SSM and set ICBUND to -1. It should work then. Hope it helps. Michal
