Known Issues

  • iMOD TUTORIALS
  • MetaSWAP (unsaturated zone) 

version iMOD5.2

(the iMOD team considers the release of an intermediate bug fix version) 

  • iMOD GUI
    • 3D Viewer
      In some cases, the lowest element of a loaded geological model or the lowest part of a bore log is missing in the display.
    • Simulation Manager
      The snap option in the tab Space Dim. can yield model coordinates larger than the dimensions of the input files. This results in an error when running the model.
      A work around is to deselect the snap option or to define interactively a smaller spatial dimension. An even better alternative is to use the iMOD batch option to start a model (see chapter 8.7.5 RUNFILE-Function).
  • iMOD BATCHFUNCTIONS
    • RUNFILE-Function. During the conversion of a RUN file to a PRJ file, a part of the CAP section is missing in the new PRJ file.  
      > Workaround: manually add the user defined extra MetaSWAP files to the (CAP) section in the PRJ file:
      007,EXTRA FILES
      D:\IMOD-MODELS\input\CAP\PARA_SIM.INP
      .....(5 lines) ...
      D:\IMOD-MODELS\input\CAP\FACT_SVAT.INP
    • IDFTIMESERIES. If points in IPF1 are outside the analyzed IDF, the function writes a NODATA value in the created associated text files. Unfortunately the NODATA value in the header of the file is zero and not set equal to the NODATA value of the IDF. This causes issues in postprocessing of the files (e.g. display in the GUI).  This error occurs only if your IPF1 file contains only points and NO associated text files. 
      > Workaround. 1) Remove points from file IPF1 that are located outside your IDF to avoid NODATA values in associated files. 2) If NODATA values occurs within a timeseries, the only option is to change the header manually or with a script. 3) You can also consider adding dummy associated files to your IPF1.  
  • iMOD TUTORIALS
    • Tutorial 15: MODFLOW6
      In steps 64 and 66 the given location/name of the MODFLOW6 output is not correct. The IDF files are saved in folder "{path of installfolder}\IMOD_USER\MODELS\MF6-FIRST-MODEL \GWF_1\GWF_EXCHANGE\GWF_1_L1_GWF_2.IDF" etc.
  • iMOD-WQ
    • In a situation in which the code is used for density-dependent flow without transport (the BTN package is not used), the time step length is always kept constant to that of the first stress period. This will be corrected in the next version

    • No space in root names and model names
      Since iMOD5.2, iMOD-WQ can handle spaces in root names and model names. However, using iMOD GUI for creating the iMOD-WQ model files, quotes are missing in the file names referenced to in the FTL file. For that reason we advice to install iMOD in a folder without a space, e.g. "c:\iMOD\version5.2". A model name cannot have a space and must contain at least one character; so no values only allowed for model name.
