GMS:What's New in GMS 8.3

The following is a start at a list of the more significant changes that will be introduced in GMS 8.3.

1. MODFLOW MNW2

   • GMS 8.3 will support the MODFLOW MNW2 package.

2. MODPATH Color Pathlines by Cell Zone Code

   • A new MODPATH display option has been added to color pathlines by the zone code the line is in. The color of the pathline will change as it hits different zone codes. This can be used to show when pathlines enter different layers, or other grid areas.

3. MODPATH Starting Locations from 3D Scatter Points and Vice Versa

   • It will be possible to convert 3D scatter points to MODPATH starting locations and vice versa.

4. Shapefiles -> 3D Scatter Points and vice versa

   • Previously you could create 2D scatter points from point shapefiles, and export 2D scatter points to shapefiles. Now we've expanded this to 3D scatter points. Furthermore, if the shapefile is 3D (z enabled) the z values will be transferred to the 3D scatter points.

5. ISTCB2 Option in MODFLOW SFR Package Supported

   • A long overdue feature in GMS has been implemented - support for the ISTCB2 option in the MODFLOW SFR package. Now GMS will turn this option on by default so that flows out of each stream reach are included in the CCF info and work the same as other CCF data. The option to save the information as a text file is also supported.

6. Improved water table display

   • The water table display option, available in ortho mode, side view, has been updated to handle MODFLOW-NWT solutions and to give a more appealing display.

7. SEAWAT tutorials

   • New SEAWAT tutorials review more of the options available in SEAWAT.

8. MT3D Steady State Stress Periods

   Support for steady state MT3D stress periods is now supported.

9. No License Required for Community Edition

   • GMS will now work in a limited mode without any license. Previously this mode was called "Community Edition" but it required a license (which could be obtained for free). Now you can download and install GMS and it will work in this limited mode as soon as it is installed - no license required.

10. Report A Bug

    • Bugs are easier to report and get fixed with the new Report A Bug command in the Help menu.
