[]Struct lumol::energy::Harmonic

pub struct Harmonic {
    pub k: f64,
    pub x0: f64,
}

Harmonic potential.

$$ V(x) = \frac{1}{2} k (x - x_0)^2 $$

where $x_0$ is the distance equilibrium, and $k$ the elastic constant.

Examples

let potential = Harmonic { x0: 2.0, k: 100.0 };
assert_eq!(potential.energy(2.0), 0.0);
assert_eq!(potential.energy(3.0), 50.0);

assert_eq!(potential.force(2.0), 0.0);
assert_eq!(potential.force(1.5), 50.0);

Fields
