NEW version of HGS PREMIUM September 2025 (REVISION 2870)
The HydroGeoSphere Revision 2870 (September 2025) software update is now available for download.
This month’s update brings targeted bug fixes, improvements to error handling, and several enhancements to hgs2vtu output options. New commands also expand the flexibility of polygon tracking and water balance reporting, making it easier to analyze results and streamline workflows in HydroGeoSphere (HGS).
Fix for polygon tracking Tecplot output
Resolved a bug that caused duplicate nodes to be reported when exporting polygon tracking node selections.
Fixes for unsaturated function commands
Corrected issues in the unsaturated brooks-corey functions and unsaturated van genuchten functions commands when issued in the grok file.
(Note: the versions of these commands in material property files remain unaffected.)
Transport mass balance fix
Addressed a bug in the computation of solute exchange variables PM2Olf(Disp), Dual2Olf(Disp), and PM2Frac(Disp) that appear in the transport mass balance.
Improved error handling
Execution errors now produce cleaner output and error handling, improving usability and reducing clutter when simulations terminate early.
hgs2vtu enhancements
Fixed a bug that caused incorrect species names and types to be assigned for the second solute onwards when multiple solutes were defined.
Reorganized the --help command output to group commands by output type for easier navigation.
Updated the hgs2vtu documentation in the Reference Manual to reflect this new organization.
New command --initial-time reports the initial time of a simulation.
New commands --cum-water-balance-csv and --cum-water-balance-tecplot generate a cumulative water balance from an existing output file for each time range specified in an ASCII input file.
New polygon tracking functionality
A new command nodal fluid mass balance for selected nodes from multifeature shp file enables polygon tracking areas to be defined using surface nodes contained within shapefile polygons, providing more flexibility for surface-based water balance reporting.
Documentation updates
The Reference Manual (hydrosphere_ref.pdf) has been updated with details on these new commands and functionality.
You can find details about these new features in the HydroGeoSphere Reference Manual. And 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!
