Struct LogProfile 

pub struct LogProfile { /* private fields */ }

Log-law boundary layer: u(z) = u_ref · ln(z/z0) / ln(z_ref/z0), z > z0; zero below z0. Constant direction with height.

The field reads only the height (position_m.y), which must be the height above the ground; HeightOffset converts another frame’s heights. Vertical wind is zero.

Implementations

impl LogProfile

pub fn new( reference_speed_mps: f64, reference_height_m: f64, roughness_m: f64, direction_from_deg: f64, ) -> Result<LogProfile, WindFieldError>

Build a log-law profile.

reference_speed_mps must be finite and >= 0, reference_height_m finite and > 0, roughness_m (z0) finite, > 0 and below the reference height, and direction_from_deg finite.

pub fn reference_speed_mps(&self) -> f64

Wind speed at the reference height, m/s.

pub fn reference_height_m(&self) -> f64

Reference height, metres.

pub fn roughness_m(&self) -> f64

Aerodynamic roughness length z0, metres.

pub fn direction_from_deg(&self) -> f64

Wind-FROM direction, degrees (constant with height).

pub fn speed_at(&self, altitude_m: f64) -> f64

Wind speed (m/s) at an altitude: zero at or below the roughness length, and for a NaN or infinite altitude (the log law has no finite value there).

pub fn wind_at( &self, altitude_m: f64, ) -> Matrix<f64, Const<3>, Const<1>, ArrayStorage<f64, 3, 1>>

Wind (m/s) at an altitude.
