NEW version of HGS PREMIUM November 2025 (REVISION 2888)

The HydroGeoSphere Revision 2888 (November 2025) is now available for download.

This month’s update includes targeted refinements to post-processing workflows, improved warning message handling, and two new Tecplot export commands to support easier visualization and model interpretation. These changes are designed to reduce clutter during model setup and provide clearer tools for examining initial conditions and porous medium zone geometry.

New and updated commands (see hydrosphere_ref.pdf)

• New command porous medium zone isopach to tecplot
  - Generates an isopach map (zone thickness map) for porous medium zones in Tecplot ASCII format.
  - This provides the same output as the existing hsplot command plot pm zone isopach structure, now accessible directly from grok.

• New command initial head to tecplot
  - Exports initial head and pressure head fields to Tecplot ASCII format for the active model domain.
  - For variably saturated models, initial saturation is also included when applied to the porous medium domain.al head from a user-specified water saturation value across a chosen set of nodes, providing more flexibility when defining starting conditions.

Fix for model prefixes beginning with “o” in hgs2vtu

• Resolved a bug that caused issues when processing output files for models where the model prefix began with the letter “o”.

Reduced unnecessary warning message output

• Removed file overwrite warnings generated during node, face, and segment set creation.

• This helps prevent important warnings from being buried under a large volume of routine messages.

Documentation updates
The HydroGeoSphere Reference Manual (hydrosphere_ref.pdf) has been updated to include these new commands.

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!

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