UTCI (Simulation) - [source code]
Compute annual probe-specific UTCI from simulation outputs: MRT and wind-speed data trees, plus air temperature and relative humidity. For a weather-only calculator, use "UTCI (Weather)".
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| MRT | M | The MRT component's Result (preferred), or a DataTree of annual MRT values — {probe}(8760) or {hour}(probes), both accepted. | Generic Data |
| Wind Speed | V | Wind speed as an AnnualWindField (the VAF component's Wind Speed output — fed by CFD probe vectors or the ML Wind Predictor alike), one spatial list (one value per probe, held for all hours), or a {probe}(hours) / {hour}(probes) tree. An AnnualWindField on a different grid than the MRT sensors is resampled by nearest neighbor when both carry points. Pedestrian-height speeds are lifted to the 10 m UTCI reference. Defaults to calm (0.5 m/s) when unconnected. | Generic Data |
| Air Temperature | T | Annual hourly ambient air temperature (8760 values, °C). | Number |
| Relative Humidity | RH | Annual hourly relative humidity (8760 values, %). | Number |
| Transpose | Orientation of the UTCI tree output. Hours × Probes (default): one branch per hour, each holding every probe's value. Probes × Hours: one branch per probe, each holding that probe's year. | Text | |
| Run | R | Enable UTCI calculation. | Boolean |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| UTCI | U | UTCI data tree. Default: {hour}(probes). With Transpose off: {probe}(hours). Only built while this output is WIRED: for a few thousand probes the full year is tens of millions of values on the canvas, and constructing them — not the UTCI math — is the wait. Prefer the Result output with Deconstruct UTCI. | Number |
| Comfort Hours | H | No-thermal-stress hours per probe. | Integer |
| Comfort % | % | Comfort percentage per probe. | Number |
| Result | The complete annual UTCI solve as ONE item — feed to Deconstruct UTCI for statistics, comfort maps and hour selections without materializing the year as a tree. Carries the MRT probes' positions when the MRT input was a Result. | Generic Data |
