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