Features of GHE Analysis
Key Updates and New Features
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.
- Bug fixes and stability: Minor bugs resolved and overall stability improved.
