NEW version of HGS PREMIUM July 2025 (REVISION 2853)

The HydroGeoSphere Revision 2853 (July 2025) software update is now available for download.

This month’s update focuses on runtime performance, with a major overhaul of the data layout of all binary output files for vector/tensor fields (e.g., prefixo.v_pm.XXXX, prefixo.ElemK_pm.XXXX, etc.) to use a structure of arrays format. This update will result in significant increases to model runtimes by improving the read/write operation to these files. As well, users can expect a significant reduction in total file size for these binary output files (40% reduction in size for files with 4-byte real vector field with three components, 25% reduction in size for files with 8-byte real vector field with three components).

If you have any custom scripts or tools that require you to keep the legacy file format in place don’t worry, we have introduced a simple command (use legacy file format) that causes grok and HGS to generate binary output files using the original (legacy) data layout

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.
