PALM Domain - [source code]
Define the PALM-4U grid: cells, spacing and the site's latitude/longitude. The domain's lower-left corner sits at the Origin point in the Rhino model (world origin by default), with y pointing north. Feed the output to PALM Case and PALM Run.
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Latitude | Lat | Latitude of the domain's lower-left (south-west) corner, decimal degrees. Drives the sun position for radiation and comfort. | Number |
| Longitude | Lon | Longitude of the domain's lower-left corner, decimal degrees east. | Number |
| Cell Size | dx | Horizontal grid spacing in metres. PALM-4U urban runs use square cells (dx = dy); 2 m resolves streets and courtyards, 4–10 m a district. | Number |
| Cells X | nx | Number of cells across the domain in x (east). | Integer |
| Cells Y | ny | Number of cells across the domain in y (north). | Integer |
| Cells Z | nz | Number of vertical levels. The domain top should clear the tallest building by a factor of 3 or more. | Integer |
| Vertical Spacing | dz | Vertical grid spacing in metres. Empty follows Cell Size, which is what a street-resolving run wants. | Number |
| Origin | O | Rhino model point of the domain's lower-left corner. Default 0,0,0. | Point |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| Domain | D | The PALM domain. Feed to PALM Case, which rasterizes the scene onto it and writes the run. | Generic Data |
| Boundary | B | The domain footprint as a rectangle in model space — what the static driver will rasterize. | Curve |
| Summary | S | Grid, extent and anchor, one line each. | Text |
