Struct Rk4Solver 

Source 
pub struct Rk4Solver;
Expand description

4th-order Runge-Kutta integrator.

Much better energy conservation than semi-implicit Euler for systems with configuration-dependent mass matrices (e.g., double pendulum).

Trait Implementations§

Source§

impl Solver for Rk4Solver

Source§

fn step(&self, model: &Model, state: &mut State)

Advance state by dt. Reads from state and writes the result back.
Source§

fn step_with_jacobians(&self, model: &Model, state: &mut State) -> StepJacobians

Advance state by dt and return step Jacobians.
