GMS:What's New in GMS 8.2

The following is a start at a list of the more significant changes that will be introduced in GMS 8.2.

1. MODFLOW-NWT

   • GMS 8.2 will support MODFLOW-NWT including the UPW and NWT packages.

2. MODFLOW DE4 Package
3. MODPATH changes in saving files

   • Automatically running MODPATH is now optional. GMS saves MODPATH files with the project, and reads in the pathline solutions when reading the project (instead of having to always recompute them).
   • A new Pathlines to Arcs command converts MODPATH pathlines to feature arcs

4. ZONEBUDGET

   • Although GMS has provided it's own zone budgeting tools for a long time, now it will include a user-friendly interface to run the USGS's own ZONEBUDGET program. A new tutorial is also provided on how to use this interface.

5. Export 3D Grids as Shapefiles

   • A quick and easy way to get your 3D grid - including the current dataset and cell activity - into ArcMap (or any other software that can read shapefiles).

6. CCF → Velocity vectors

   • GMS now computes velocity vectors from MODFLOW CCF data taking into account the porosity and saturated thickness.

7. New tutorials

   • MODFLOW-NWT tutorial
   • ZONEBUDGET tutorial
