Terrain

- [source code]

Create a Terrain object representing the land on which an urban area sits.

This includes both the geometry and the properties of the pavement within the urban area.

Inputs

• terrain_geo [Required]

  An array of Breps or meshes that together represent the terrian. This should include the entire area of the site, including that beneath building footprints.

• albedo

  A number between 0 and 1 that represents the albedo (reflectivity) of the pavement. (Default: 0.1, typical of fresh asphalt).

• thickness

  A number that represents the thickness of the pavement material in meters. (Default: 0.5 meters).

• conductivity

  A number representing the conductivity of the pavement material in W/m-K. (Default: 1 W/m-K, typical of asphalt).

• vol_heat_cap

  A number representing the volumetric heat capacity of the pavement material in J/m3-K. This is the number of joules needed to raise one cubic meter of the material by 1 degree Kelvin. (Default: 1.6e6 J/m3-K, typical of asphalt).

Outputs

• terrain

  A Terrain object that can be plugged into the "DF Assign Model UWG Properties" component to specify the terrain of an urban area.
