Console
The console reports every number produced by the interpretation. It is organised as three independent pages, reached with the buttons at the bottom of the panel, and the three pages share a common footer reporting computation times. The console updates live: moving a phase boundary or a calibration slider changes the figures below as the mouse moves.
The console doubles as the help viewer: clicking the help button of any panel replaces the results with the help page of that panel, and clicking one of the page buttons below brings the results back.
of any panel replaces the results with the help page of that panel, and clicking one of the page buttons below brings the results back.The page follows the node. Selecting a node in the analysis tree brings up the console page that belongs to it: TRT data and Undisturbed temperature both open the first page, FOA model the second, Short-term g-function the third. The buttons can still select any page at any time.
Page 1, Phase statistics and undisturbed temperature - Reached with the button. The upper block characterises each of the three phases of the test, circulation, heating and recovery, in its own column: the duration (h), the mean fluid temperature (°C), the mean heating power (W), the coefficient of variation of that power (Q variation, CV, in %), the mean unit power (W/m), the mean flow rate (L/min) and the Reynolds number. The mean fluid temperature is the average of the inlet and outlet readings over the phase, and it is the temperature at which the fluid properties of that phase, and with them the resistance breakdown of the test borehole, are evaluated. Q variation, CV, is the standard deviation of Q over the phase divided by its mean, reported as a percentage. It is computed on the measurements as imported, not on the smoothed signal, since a low-pass filter of n samples reduces the scatter by roughly √n. The mean, which the filter does not change, is taken from the filtered signal.

The mean, which the filter does not change, is taken from the filtered signal.The Reynolds number is that of one downward leg of the test borehole, so it accounts for the pipe configuration entered on the Test borehole panel: a double U-loop splits the flow between two legs, and a coaxial probe carries it in the annulus. It is the same value as on the Heat carrier fluid panel for the same phase.
The lower block, under the separating rule, reports the undisturbed ground temperature Tg (°C) and, where a vertical profile has been analysed, the mean annual ground temperature Ta (°C). It carries four columns: the first three are the three determination methods of the Undisturbed temperature panel, Manual, Circulation and Vertical, shown side by side whichever one is currently selected. A method that cannot produce a value on the loaded data shows a dash; the Circulation column, in particular, stays empty when the test has no circulation phase or when both fluid probes are hidden. The fourth column, Model, shows the Tg value its slider currently carries. Manual entry and the short-term g-function produce no Ta, so those cells stay blank.
Page 2, FOA regression results - Reached with the button. Presents, side by side, the results of the heating-phase and recovery-phase regressions: the ground thermal conductivity λs (W/m·K), the effective borehole resistance Rb* (m·K/W) and the critical time tcr (h), which is the value marked by the red line on the regression charts. The recovery column carries no borehole resistance, since Rb* is recovered from the heating-phase intercept and the recovery phase supplies only a slope.

The recovery column carries no borehole resistance, since Rb* is recovered from the heating-phase intercept and the recovery phase supplies only a slope.A further row, Residual RMSE, reports the root mean square of the regression residuals over the fitted window, in °C. The residual histogram of the FOA panel shows their distribution; their mean and sample standard deviation are given in the CSV export.
Page 3, Short-term g-function results - Reached with the button. Lists the current value of every calibrated parameter, λs (W/m·K), Cs (MJ/m³·K), λg (W/m·K), Cg (MJ/m³·K), the shank spacing s (m) and Tg (°C), each conductivity/capacity pair followed by the thermal diffusivity α = λ/C (m²/s) it implies. Below that, an experimental effective borehole resistance Rb* (m·K/W), computed by the same multipole method as the Test borehole panel but from these calibrated values rather than the entered ones, and a Residual RMSE row giving the root mean square of the residuals between the measured and the simulated fluid temperature, in °C. As on the previous page, their mean and sample standard deviation are exported to CSV rather than shown here.

With the default excitation both depart from their measurement by the same amount; with the Q/(V·Cf) excitation the two departures differ and the statistics describe their mean. The residual histogram in the model's panel shows the same residuals as a distribution.
Computation time - The footer shared by every page reports the wall-clock time of each stage of the interpretation pipeline. Data covers building the time vector, applying the low-pass filter and splitting the record into its phases; FOA covers the two linear regressions; g-func covers the spectral convolution of the borehole's response with the measured heat-injection history; and Chart covers redrawing the temperature series. The labels are drawn in red while a computation is running and turn black once it completes.
