Struct MacroState 

pub struct MacroState {
    pub density: f64,
    pub momentum: [f64; 3],
    pub energy: f64,
}

Macroscopic state at a single spatial cell: density, momentum, energy.

Fields

density: f64

Mass density ρ = ∫ f dv³

momentum: [f64; 3]

Momentum density J = ρu = ∫ v f dv³ (3 components)

energy: f64

Energy density e = ½ ∫ |v|² f dv³

Implementations

impl MacroState

pub fn velocity(&self) -> [f64; 3]

Bulk velocity u = J/ρ.

pub fn thermal_energy(&self) -> f64

Thermal energy density: e_th = e - ½ρ|u|².

pub fn pressure(&self) -> f64

Isotropic pressure P = (2/3) * e_th (for 3D Maxwellian).

pub fn temperature(&self) -> f64

Temperature T = P/ρ = (2/3) * e_th/ρ.
