Struct Junction 

pub struct Junction {
    pub demands: Vec<DemandCategory>,
    pub emitter_coeff: f64,
    pub emitter_exp: f64,
}

An ordinary demand node whose head is solved at each hydraulic step (§2.4.2).

Fields

demands: Vec<DemandCategory>

Demand categories attached to this junction (§2.5).

emitter_coeff: f64

Emitter discharge coefficient Ke (m³/s per m^ne); 0 = no emitter.

emitter_exp: f64

Emitter pressure exponent ne; default 0.5.

Implementations

impl Junction

pub fn total_demand( &self, t: f64, opts: &SimulationOptions, patterns: &[Pattern], pattern_index: &HashMap<String, usize>, ) -> f64

Total instantaneous demand at time t (§2.5).

$D_i(t) = \sum_k \text{base}k \times D{\text{mult}} \times F_{\text{pattern}}(t)$

The pattern lookup procedure:

1. Use the demand category’s own pattern ID if set.
2. Otherwise fall back to default_pattern from options (if set).
3. Otherwise use multiplier 1.0.

Trait Implementations

impl Clone for Junction

fn clone(&self) -> Junction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Junction

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
