Struct PvtEos 

pub struct PvtEos {
    pub cold_eos: BirchMurnaghan3Eos,
    pub gruneisen: GruneisenParameter,
    pub cv: f64,
    pub t0: f64,
}

Simple P-V-T EOS combining Murnaghan cold compression with Grüneisen thermal.

p(V,T) = p_cold(V) + Γ(V)/V * cv * (T - T₀)

Fields

cold_eos: BirchMurnaghan3Eos

Cold compression EOS (Birch-Murnaghan 3rd order).

gruneisen: GruneisenParameter

Grüneisen parameter model.

cv: f64

Specific heat at constant volume cv (J/(kg·K)).

t0: f64

Reference temperature T₀ (K).
