Analysis Suite — Release Notes
Every version of every module, newest first.
Version 3.0Version 3.0
A diagnostics panel for the test record
- Diagnostics — Reynolds number and flow-regime flag for each phase, histograms of heating power, flow rate and model residuals, and the residual mean, standard deviation and RMSE
- Values read off any curve or histogram bar on hover, and a scaled cross-section of the test borehole
- 43 verification scenarios, run from the application, each against a published reference and its own tolerance
- Numbered 3.0 with the suite. TRT Analysis has been distributed since 2023 and its published methods go back further; from this release it carries the version number of the platform it ships in, whose kernel, fluid properties and project file it shares
Version 3.0Version 3.0
The thermal plume in motion, and the Sankey diagram
- The thermal plume is now transient — it evolves across the design horizon instead of showing a single frozen picture, and it is computed substantially faster
- Film the plume: one button writes an animated GIF covering the simulated duration in 450 frames, each stamped with the elapsed time
- Annual energy balance as a Sankey diagram — a year of operation in one picture: where the energy comes from, and where it ends
- Measurably faster: the entering-fluid-temperature solver converges in fewer iterations, and the chart views redraw several times quicker on large fields
- Verification scenarios run from the application, each reporting whether the g-function converged
Version 2.4
Geocooling and Domestic Hot Water
- Geocooling (passive cooling) — bypass the heat pump in cooling mode via a heat exchanger
- Domestic hot water (DHW) — loads integrated into simulation for both heating and cooling modes
- Data import and copy-paste — borehole coordinates, heat pump performance curves, and thermal load profiles
Version 2.3
Standing Column Well Support
- Standing column well (SCW) — full sizing and simulation for a GHE composed of 1 SCW
- Extended borehole depth up to 500 m for all configurations (coaxial, single U-loop, double U-loop, SCW)
- Improved performance for large GHEs (>300 boreholes) — simulation kernel 2–3× faster
- Data export issue resolved
Version 2.2
Hourly Simulation from 1 to 50 Years
- Hourly simulations for design horizons of 1, 3, 5, 10, 15, 20, 25, and 50 years
- Customizable chart views
- Chart rendering performance improved by a factor of 3–20×
- Simulation kernel automatic optimization after first use
- Stability fix — fatal crash from version 2.1 resolved
Version 2.1
Thermal Plume Visualization
- Thermal plume viewer — 2D visualization of the spatial extent and evolution of the subsurface thermal plume
- Ground temperature evaluation at user-defined locations
- Extended GHE sizing periods — 25, 50, and 100-year horizons added
- Improved undisturbed ground temperature model based on surface temperature and geothermal heat flux
Version 2.0
Inclined Boreholes with Groundwater Flow
- Inclined boreholes with groundwater flow — inclined finite line source model with full groundwater flow support
- 3D borehole viewer — inspect borehole layouts, orientations, and depths within the interface
- Interface and font rendering improvements across platforms
- Address finder and mapping utility (development preview)
Version 1.4
Extended Borehole Field Support
- Large borehole field support — regular and irregular fields from 1 to 625 boreholes
- Improved GUI responsiveness — smoother and faster user interaction
- Dark theme refinements for cleaner, more consistent appearance
- Stability fix — critical crash when sizing tool was used before load initialization resolved
- New installer for streamlined installation and setup
Version 1.3
Coaxial BHE and Spreadsheet Export
- Coaxial borehole heat exchangers — added alongside single and double U-loop configurations
- Spreadsheet export — simulation results exportable for custom charts and further analysis
- Improved convective heat transfer modeling in the transition zone (2300 < Re < 4000)
- Borehole resistance calculation up to 3× faster
- Validation against more than 100 published reference scenarios
Version 1.2
Faster Simulation and Chart Tooltips
- Fluid temperature simulation 3× faster
- Chart tooltips for easier data interpretation
- Expanded groundwater flow velocity range
- Borehole coordinate copy directly from table
- Minor features, GUI improvements, and bug fixes
Version 1.1
Flexible Load Input and Faster G-Functions
- G-function evaluation 2.5× faster — 40 ms for 100-borehole fields on most desktops
- Flexible load input — monthly base and peak loads in addition to hourly profiles
- COP input — direct entry of GSHP coefficient of performance and manufacturer data
- Minor features, GUI improvements, and bug fixes
Version 3.0Version 3.0
First release of GLN Analysis
- Draw the network as a piping and instrumentation diagram: a node for every component, an edge for every pipe, with more than forty component types in five families. A complete borehole field is generated from a count, a spacing and a depth
- Newton-Raphson solution of the mass balance at every free node, Darcy-Weisbach distributed losses with a Swamee-Jain friction factor, and minor losses seeded by component type from published values
- Elevation handled as piezometric head, so the hydrostatic column of a 150 m borehole loop is handled correctly
- Pump library described by manufacturer H-Q points, with variable-speed control at constant speed, constant head or imposed flow
- Velocity and friction gradient flagged against the recommended windows, a balancing indicator that detects borehole U-loops geometrically, and Reynolds number per element
- Reference scenarios shipped with the module, checked against hand calculations and published worked examples
Version 3.0Version 3.0
One application and one project file
- TRT, GHE and GLN are now one application: a single download, a single installation, and one project file that carries all three modules together
- Carry a result from one module to the next. A thermal response test hands its ground conductivity and undisturbed temperature to the sizing, and a sized field hands its geometry to the network. A test yields one conductivity per method, so you choose which one is carried over, with the fit quality of each shown side by side
- macOS. The suite now runs on macOS 26 and later as well as Windows 10 and 11 — the same application, the same project files, moved between the two
- Fluid properties, the project record and the console are shared by the three modules, so a fluid chosen once is the fluid every module computes with
- Licensing by project size, not by module. Three annual tiers set by how large a system you design; every tier carries the same physics and the same solver
- Consultation mode. A project file always opens — at any size, in every module, with no licence or with one that has lapsed. It recomputes, draws every chart and prints; what a licence buys is the right to change a project and save it. A project larger than your tier opens the same way rather than being refused, and names the measurement that exceeds the ceiling. A design you deliver therefore remains readable by whoever receives it, at no cost
