Enum ForceModelKind 

pub enum ForceModelKind {
    TwoBody {
        mu_km3_s2: f64,
    },
    TwoBodyJ2 {
        mu_km3_s2: f64,
        re_km: f64,
        j2: f64,
    },
    Composite {
        components: ForceModelComponents,
    },
}

Which force model supplies the acceleration during propagation.

The legacy variants carry their own physical parameters so a caller can propagate a non-Earth central body by supplying a different gravitational parameter. The Self::two_body / Self::two_body_j2 constructors fill in the canonical Earth values from crate::astro::constants. The Self::Composite variant adds optional force components without changing those legacy branches.

Variants

TwoBody

Pure two-body (Keplerian) gravity.

Fields

mu_km3_s2: f64

Gravitational parameter, km^3/s^2.

TwoBodyJ2

Two-body gravity plus the J2 oblateness perturbation.

Fields

mu_km3_s2: f64

Gravitational parameter, km^3/s^2.

re_km: f64

Reference equatorial radius, km.

j2: f64

J2 zonal harmonic coefficient (dimensionless).

Composite

Additive composition of central gravity and optional perturbations.

Fields

components: ForceModelComponents

Force components to add.
