GMS:What's New in GMS 10.8

The following is a list of the more significant changes that will be introduced in GMS 10.8.

1. HydroGeoSphere interface added
2. MODFLOW 6
   • Flow Budget
   • Velocity vectors
   • HFB package, map from coverage
   • Starting heads = top elevations option
   • Units in table column heading tool tips
   • Open in Explorer command
3. MODFLOW
   • MODFLOW BCF package support for IKCFLAG
   • “SAMG-Modflow” and “SAMG-Modflow+ Add-on”
4. MODFLOW-USG
   • Find and set pass through cells for MODFLOW-USG DISU package
   • DRT and ETS enabled
   • RCH, EVT, ETS packages allow the use of 3D Datasets to define input arrays.
   • The RCH, EVT, and ETS Packages offer a method to populate input array values from one or more rasters using the Rasters to Array feature(structured and unstructured grids).
5. MODFLOW-USG Transport
   • Find and set “pass-through cells” for the MODFLOW-USG DISU Package
   • DRT & ETS Packages now fully supported for MODFLOW-USG Transport
   • RCH package support for SEEPELEV and CONCENTRATION
   • EVT package support for ETFACTOR
   • RCH, EVT, ETS packages allow the use of 3D Datasets to define input arrays. Previously there was only an option to use 2D Datasets on matching 2D structured grids
   • The RCH, EVT, and ETS Packages offer a method to populate input array values from one or more rasters using the Rasters to Array feature. (structured and unstructured grids)
   • DRT and ETS enabled
6. General
   • New color ramp dialog with about 200 new ramps from Colorcet and MatPlotLib
   • 3D UGrid from Rasters tool
   • Ability to handle non-English characters in datasets
   • List of selected UGrid cell/point IDs shown in selection feedback
   • Legend can include dataset units and time units via UNITS and TUNITS in Contour Legend Options dialog
   • Map to WASH tool
   • Select all cells in UGrid layer using ‘l’ (L) key
7. New Tutorials
   • HydroGeoSphere – Surface Flow and Evapotranspiration
   • HydroGeoSphere – Porous Media Domain
   • HydroGeoSphere – Post-Processing
   • MODFLOW 6 MDT 3D
