Struct VinetEos 

pub struct VinetEos {
    pub v0: f64,
    pub k0: f64,
    pub k0_prime: f64,
}

Vinet (Universal) equation of state for solids.

p(V) = 3 K₀ * x^(-2) * (1 - x) * exp(η(1-x)) where x = (V/V₀)^(1/3), η = (3/2)(K₀’ - 1).

Fields

v0: f64

Reference specific volume V₀ (m³/kg).

k0: f64

Bulk modulus at zero pressure K₀ (Pa).

k0_prime: f64
