Enum Phase 

pub enum Phase {
    Initialization,
    SteadyState,
}

Which phase of JEOD’s runtime is being mirrored when evaluating ground contact.

JEOD’s BodyRefFrame::state.trans.position for a surface-model vehicle_point is default-constructed (0, 0, 0) and only populated by DynBody::compute_vehicle_point_states at a specific point during initialization — after ContactGround::initialize_ground has already run. The two phases see different state and produce different forces; both are needed to reproduce JEOD’s CSV trajectory.

Variants

Initialization

Pre-propagation initialization-time evaluation. JEOD’s GroundInteraction::initialize → in_contact() call runs here. Produces an impulsive contact force that is consumed at stage 1 of step 1 (RK4 weight 1/6) and zeroed thereafter by ContactSurface::collect_forces_torques.

SteadyState

Post-propagation steady-state evaluation. JEOD’s check_contact_ground() derivative-class job runs here on every RK4 stage. For vehicles above (or at) the planet surface this reports no contact in JEOD’s algebra — and physically.

Trait Implementations

impl Clone for Phase

fn clone(&self) -> Phase

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Phase

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Phase

fn eq(&self, other: &Phase) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Phase

impl Eq for Phase

impl StructuralPartialEq for Phase
