Struct Euler 

pub struct Euler {
    pub config: OdeSolverConfig,
    /* private fields */
}

Explicit first-order Euler solver with adaptive step size. Maps to Foam::Euler (which inherits from adaptiveSolver).

Fields

config: OdeSolverConfig

Implementations

impl Euler

pub fn new(n: usize, abs_tol: f64, rel_tol: f64) -> Self

pub fn solve_step( &mut self, ode: &dyn OdeSystem, x: &mut f64, y: &mut Vec<f64>, dx_try: &mut f64, ) -> Result<(), OdeError>

Take one adaptive step. On return x and y are updated and dx_try holds a suggested step size for the next call.

pub fn integrate( &mut self, ode: &dyn OdeSystem, x_start: f64, x_end: f64, y: &mut Vec<f64>, dx_est: &mut f64, ) -> Result<(), OdeError>

Integrate from x_start to x_end.
