Struct RadiationNetwork 

pub struct RadiationNetwork {
    pub n: usize,
    pub temperatures: Vec<f64>,
    pub emissivities: Vec<f64>,
    pub areas: Vec<f64>,
    pub view_factors: Vec<f64>,
}

N-surface radiation network (gray, diffuse enclosure).

Solves the full N×N radiosity system for a closed diffuse gray enclosure. The net heat flow on each surface is computed from the radiosity vector.

Reference: Incropera et al., “Fundamentals of Heat and Mass Transfer”.

Fields

n: usize

Number of surfaces.

temperatures: Vec<f64>

Surface temperatures [K].

emissivities: Vec<f64>

Surface emissivities (0–1).

areas: Vec<f64>

Surface areas [m²].

view_factors: Vec<f64>

View factor matrix F[i][j] (row-major, n×n).

Implementations

impl RadiationNetwork

pub fn new( temperatures: Vec<f64>, emissivities: Vec<f64>, areas: Vec<f64>, view_factors: Vec<f64>, ) -> Self

Create a new radiation network.

pub fn f(&self, i: usize, j: usize) -> f64

View factor F[i][j].

pub fn net_heat_flow_simple(&self, i: usize) -> f64

Net heat flow from surface i [W] using the radiosity method.

Simplified: q_i = ε_i·A_i·σ·(T_i⁴) - A_i·sum_j(F_ij · ε_j·σ·T_j⁴)

This is the optically-simplified (no inter-reflection) version.

pub fn emitted_power(&self, i: usize) -> f64

Total radiative power emitted by surface i [W].
