Features of GHE Analysis

Key Updates and New Features

Version 2.2 – Hourly Simulation from 1 to 50 years (March 24, 2026)

This release introduces expanded simulation and visualization capabilities, further enhancing the power and usability of GHE Analysis.

 

• Hourly simulations for 1 to 50 years: Added full hourly simulation support for design horizons of 1, 3, 5, 10, 15, 20, 25, and 50 years. This enhancement aligns GHE Analysis with most international GHE design standards and allows for more detailed and realistic long-term system evaluation.
• Customizable charts: Users can now customize simulation charts, making it easier to tailor visualizations and ease analysis.
• Significantly faster chart rendering: Chart performance has been improved by a factor of 3 to 20, providing smoother interaction and faster data visualization, even for large simulation times.
• Simulation kernel optimization: The simulation engine is now automatically optimized after the first use of GHE Analysis, resulting in faster subsequent simulations.
• Stability improvement: Resolved a fatal crash introduced in version 2.1. We sincerely apologize for the inconvenience and thank users for their feedback.

As of version 2.2, GHE Analysis includes the following features: 

Version 2.1 – Thermal Plume Visualization Support (January 15, 2025)

This release introduces new tools for analyzing and visualizing subsurface thermal plume, along with extended sizing capabilities of GHEs.

• Thermal Plume Viewer Added: A new 2D viewer allows users to visualize the spatial extent and evolution of the thermal plume in the ground.
• Ground temperature evaluation at user-defined locations: Users can now evaluate ground temperature or temperature perturbation at specific locations, enabling more detailed and localized thermal analyses.
• Extended GHE sizing periods: The sizing tool now supports long-term design horizons of 25, 50, and 100 years, in addition to the existing 1, 3, 10 and 20-year periods.
• Improved undisturbed ground temperature model: The undisturbed ground temperature is now defined as a function of surface temperature and geothermal heat flux, improving the representation of real geological conditions.

Version 2.0 – Support for Inclined Boreholes with Groundwater Flow (November 24, 2025)

• Inclined boreholes with groundwater flow: Added full support for the inclined finite line source model, including groundwater flow effects, expanding simulation capabilities for complex borehole configurations.
• 3D borehole viewer: Introduced a new 3D borehole visualization tool, enabling users to inspect borehole layouts, orientations, and depths directly within the interface.
• Interface and aesthetic improvements: Resolved visual inconsistencies on certain systems where the correct font was not displayed correctly, ensuring uniform appearance across platforms.
• Mapping and address tools (development preview): Added an address finder and mapping utility to support upcoming features.

Version 1.4 (September 16, 2025)

• Extended support for large borehole fields: Simulation now supports both regular and irregular geothermal configurations ranging from 1 up to 625 boreholes, enabling design of commercial, institutional, and district-scale systems.
• Improved GUI responsiveness: User interactions are now smoother, faster, and more reliable.
• Dark theme enhancements: Refined aesthetics for black theme users.
• Bug fixes and stability: Fixed a critical crash linked to the sizing tool.
• New installer: A redesigned installer streamlines installation and setup.

Version 1.3 (June 9, 2025)

• Coaxial BHEs Added: In addition to single and double U-loop configurations, coaxial borehole heat exchangers are now supported, providing more flexibility for geothermal system design.
• Spreadsheet Export: Simulation results can now be exported directly to a spreadsheet, enabling users to create custom charts and perform further analysis as needed.
• Convective Heat Transfer: The modeling of the convection coefficient in the transition zone (Reynolds number 2300 < Re < 4000) has been improved for more precise simulation results.
• Faster Borehole Resistance Calculation: The computation of borehole resistance is now up to three times faster, significantly reducing simulation time.
• GHE Analysis Validation: GHE Analysis has been verified against more than 100 scenarios, using published reference values to ensure accuracy and reliability.

Version 1.2 (March 31, 2025)

• Faster fluid temperature simulation: Now 3 times faster.
• Chart tooltips: Display tooltips on certain charts for easier data interpretation.
• Expanded groundwater flow velocity: Wider range of applications for groundwater flow velocity.
• Borehole coordinate management: Copy borehole coordinates directly from the table.
• Minor features and GUI improvements: Additional small enhancements to features and interface.
• Bug fixes and stability: Minor bugs resolved and stability further improved.

Version 1.1 (February 17, 2025)

• Faster g-function evaluation: Now 2.5 times faster, running in 40 ms for 100 borehole fields on most desktop computers.
• Flexible load input: Enter monthly base and peak loads, in addition to hourly building or ground loads.
• COP input option: Directly enter the Coefficient of Performance (COP) of the GSHP, as well as manufacturer data.
• Minor features and GUI improvements: Several small enhancements to usability and interface.
