Struct OperatingNomogram 

pub struct OperatingNomogram {
    pub name: String,
    pub index_flowgate: String,
    pub constrained_flowgate: String,
    pub points: Vec<(f64, f64)>,
    pub in_service: bool,
}

A piecewise-linear operating nomogram: restricts one flowgate’s MW limit based on the real-time MW flow measured on a second “index” flowgate.

The points vector is a sorted list of (index_flow_mw, constrained_limit_mw) pairs defining the nomogram curve. evaluate(index_flow_mw) performs piecewise-linear interpolation with flat extrapolation at the endpoints.

Example

use surge_network::network::OperatingNomogram;
let nom = OperatingNomogram {
    name: "NomA".into(),
    index_flowgate: "FG_North".into(),
    constrained_flowgate: "FG_South".into(),
    points: vec![(-500.0, 1000.0), (0.0, 800.0), (500.0, 500.0)],
    in_service: true,
};
assert!((nom.evaluate(250.0) - 650.0).abs() < 1e-9);

Fields

name: String

Human-readable name.

index_flowgate: String

Name of the flowgate whose flow is used as the x-axis input.

constrained_flowgate: String

Name of the flowgate whose MW limit is tightened by this nomogram.

points: Vec<(f64, f64)>

Sorted (index_flow_mw, constrained_limit_mw) breakpoints.

Must have at least one point. Need not cover the full operating range; out-of-range inputs are clamped to the nearest endpoint (flat extrapolation).

in_service: bool

Whether this nomogram is actively enforced.

Implementations

impl OperatingNomogram

pub fn evaluate(&self, index_flow_mw: f64) -> f64

Evaluate the nomogram: return the constrained flowgate’s MW limit given index_flow_mw on the index flowgate.

Uses piecewise-linear interpolation between breakpoints, with flat extrapolation outside the defined range. Returns f64::INFINITY if points is empty (no constraint).
