Flow Rates - [source code]
Compute volumetric flow rates (m³/s) across a mesh, treating its vertices as velocity probes. Per face: average vertex velocities × face area × cos(angle to face normal).
Input
| Name | Nickname | Description |
|---|---|---|
| Velocity | U | Velocity vectors, one per mesh vertex (e.g. probed pedestrian-height wind). |
| Mesh | M | Mesh whose faces the flow is integrated over. |
Output
| Name | Nickname | Description |
|---|---|---|
| Flow Rates | Q | Volumetric flow rate per face (m³/s). |
| Centers | C | Face centers. |
| Dir | Average velocity vector per face. |
