NEW version of HGS (September 2023 - Revision 2582)

The HydroGeoSphere Revision 2582 (September 2023) is now available for download.

This month’s update is includes an exciting new transport feature (colloid transport), one major runtime efficiency improvement, new commands, new output variables, and improved handling of perched water tables (along with the usual suite of bug fixes). The development team has really outdone themselves this month, kudos!

Here’s some basic info on the really exciting stuff (as always, check the release notes for full details):

• Add colloid transport to HGS to simulate colloid attachment from the liquid to the solid phase and colloid detachment from the solid to the liquid phase for the porous medium and dual continuum domains. This new capability can be activated using the follow inventory of new commands (see the “Colloid Transport” section of the Reference Manual for more details on each command):

  • colloid transport parameters

  • zoned colloid transport parameters

  • dual colloid transport parameters

  • dual zoned colloid transport parameters

  • initial concentration solid phase

  • initial concentration solid phase from file

  • initial concentration solid phase from output file

• Optimize saturation/relative permeability lookup from unsaturated tables in HGS to improve performance and accuracy. Profiling shows up to a 20% improvement in simulation wall clock times

• New binary output files for pressure head, depth to groundwater table and surface water depth (no need to calculate these in post processing!)

• Refactor depth to groundwater computation in HGS to provide a 3D illustration of water table location and in particular, to correctly handle perched water tables.

• ‘initial snow depth from output file’ command allows users to specify the initial snow depth used by the rain and snowmelt boundary condition for each element in the surface domain from a previously generated o.snowdepth output file

As always, we are committed to the continued improvement to the user experience. Do you have suggestions for new commands or improvements to the user experience? Send your ideas to support@aquanty.com!

The latest installers are available on the HGS download page and a full list of changes/updates can be found in the release notes.
