  • GNC (Ghost Node Correction) Package for MODFLOW-USG
  • SWI (Seawater Intrusion) Package for MODFLOW-USG
  • CLN (Connected Linear Network) Process for MODFLOW-USG
  • Import of MODFLOW-USG models created outside GMS
  • Observations for MODFLOW-USG
  • Pilot points for MODFLOW-USG
  • Name file / unit number manager and improved support for unsupported packages
  • A Cell Summary text file as part of the MODFLOW solution
  • mod-PATH3DU particle tracking
  • UGrid refinement
  • UGrid isosurfaces
  • UGrid interpolation
  • UGrid vector display
  • Several new options for exporting files: VTK, Shapefiles, TOUGH2, GSF...
  • 6 new tutorials
  • ...and many more new features and user requests
See the full list of What's New in GMS 10.1.

GMS and TOUGH2

The image below comes from a poster presentation created by a GMS user, Andrea Borgia, who has been using GMS for pre- and post-processing of TOUGH2 models. Although GMS doesn't have an interface to the TOUGH2 model, Andrea has developed a workflow to make it work. In GMS 10.1 it will be possible to export UGrids to TOUGH2 MESH input files. Thanks Andrea!

    • Added a preference for changing the direction of the mini-grid increment/decrement
    • Added a preference for inverting the mouse wheel zoom direction
    • Changed it so attached cross sections are cleared but not deleted when editing a borehole
    • Added descriptions to borehole segments
    • Cross section editor plot lines can now appear in back of cross section

Improved Voronoi Grid Generation

Support for unstructured grids (UGrids) began with GMS version 10. A variety of UGrids can be created using GMS. One type of UGrid is a Voronoi grid. A voronoi grid has certain desirable characteristics related to the computational scheme of MODFLOW-USG: MODFLOW-USG assumes that connected cells are perpendicularly bisected by a line connecting the centers of the cells. Recent enhancements to GMS 10.1 include a much faster Voronoi grid generator. An example model is shown below of a voronoi grid of the Biscayne Bay model area. This grid was generated in about 30 seconds on a core i7 3.4 GHz processor. The final grid has about 200,000 cells.

MODFLOW & More 2015 conference

Alan Lemon and Norm Jones had a great time at the MODFLOW and More 2015 Conference May 31 - June 3. We didn't seem to take any pictures of the conference, but here's one from the IGWMC Facebook page and if you look closely you can just make out the edge of the Aquaveo booth off to the right of the photo. :)
