NEW version of HGS PREMIUM June 2026 (REVISION 2975)
Support Ongoing Improvements to HGS
Share your ideas to help improve the HydroGeoSphere user experience. Your feedback plays an important role in guiding future development— whether it’s new commands, workflow enhancements, or usability improvements that support more efficient integrated hydrologic modelling.
The HydroGeoSphere June 2026 release is now available for download.
This month’s update focuses on improving parallel performance, reducing memory usage, enhancing error checking, and expanding visualization and output options. Together, these updates improve model efficiency, simplify debugging, and provide new ways to export and visualize simulation results in HydroGeoSphere (HGS).
New boundary condition output command
New command csv output generates nodal flux output as a CSV file at each output time.
These CSV outputs can be readily parsed and visualized in tools such as ParaView.
New Tecplot export command
New command chosen faces to tecplot exports the current face selection to a Tecplot ASCII file.
This simplifies visualization and debugging of selected face sets.
Improved unsaturated table error checking
Enhanced error and bounds checking when reading unsaturated tables for the porous medium, dual continuum, and discrete fracture domains.
This provides more robust validation of input data and helps identify issues earlier in the model setup process.
Improved performance and memory efficiency
Refactored hgs2vtu to prevent identical warning messages from repeatedly filling the log file. Warnings are now reported once on first occurrence and then suppressed.
Refactored grok and HGS parallelization to improve parallel efficiency and reduce unnecessary memory usage.
Refactored preconditioner construction to improve memory efficiency and strengthen error checking.
Fix for boundary condition diagnostic output
Resolved a formatting issue in the diagnostic output generated by the boundary condition commands bound time-file table and bound time-file table to surface elevation offset.
This ensures clearer and more consistent reporting when using these boundary condition options.
Fix for interpolated observation points
Corrected a bug in the interpolated observation point commands that could result in values being interpolated at an incorrect z-coordinate.
This improves the accuracy of interpolated observation point outputs.
You can find details about these new features in the HydroGeoSphere Reference Manual. And as always, we are committed to the continued improvement of the user experience. Do you have suggestions for new commands or improvements to the user experience? Send your ideas to support@aquanty.com!
