Struct AdamsBashforth2 

pub struct AdamsBashforth2 {
    pub f_prev: Option<Vec<Real>>,
}

Adams-Bashforth 2-step explicit integrator.

Requires the acceleration from the previous step (f_prev). When f_prev is None the method falls back to a single Euler step.

Fields

f_prev: Option<Vec<Real>>

Stored acceleration from the previous step (optional first-step bootstrap).

Implementations

impl AdamsBashforth2

pub fn new() -> Self

Create a new Adams-Bashforth 2-step integrator.

pub fn reset(&mut self)

Reset the stored previous-step forces.

pub fn integrate_ab2( &mut self, q: &mut [Real], v: &mut [Real], f: &[Real], inv_mass: &[Real], dt: Real, )

Integrate state using the 2-step formula.

Trait Implementations

impl Default for AdamsBashforth2

impl Integrator for AdamsBashforth2

fn integrate( &self, q: &mut [Real], v: &mut [Real], f: &[Real], inv_mass: &[Real], dt: Real, )
