LBM Field - [source code]
Read the time-averaged pedestrian wind field from an LBM case directory. Outputs world-frame points and velocity vectors — plug both into the Vector Field Viewer.
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Case | C | LBM case directory (the 'Case' output of the LBM Run component). | Text |
| Refresh | R | Re-read the results (toggle while a run is in progress). | Boolean |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| Points | P | Probe points (world frame). | Point |
| Velocity | V | Time-averaged velocity per point (m/s, world frame). | Vector |
| Speed | S | Speed magnitude per point (m/s). | Number |
| Status | St | Read status. | Text |
| Spread | Sd | Per-point standard deviation of the speed across the perturbed-inflow ensemble members (m/s). Empty for a single run. High spread — typically in wakes and shear layers — means the local result is sensitive to inflow uncertainty; give comfort verdicts there extra margin. | Number |
