Struct sir_ddft::SIRDiffusion2DIVP

pub struct SIRDiffusion2DIVP { /* private fields */ }

Initial value problem for the SIR model with diffusion in two spatial dimensions

Note: The model is technically a PDE, but is transformed to a high-dimensional ODE via the finite difference method.

Implementations

impl SIRDiffusion2DIVP

pub fn new( sir_params: SIRParameters, diff_params: SIRDiffusionParameters, state: SIRStateSpatial2D ) -> Self

Creates a new IVP for the SIR diffusion model

pub fn add_time(&mut self, time: f64)

Increase integration time

pub fn get_result(&self) -> (f64, SIRStateSpatial2DBorrowed<'_>)

Get current time and state

Note that the type of the return value is not SIRStateSpatial2D, but a similar construct with references

Trait Implementations

impl<S> ODEIVP<S, f64> for SIRDiffusion2DIVP

fn rhs(&mut self, _: f64, y: &[f64], rhs: &mut [f64])

Returns right hand side (i.e. the value of f) of IVP y'=f(t,y)

fn initial_state(&mut self) -> (f64, Vec<f64>)

Returns initial state (t_0, y_0) such that y(t_0) = y_0

fn end_step(&mut self, _: f64, _: &[f64], _: &S) -> StopCondition

Called at the end of each integration step (and once for t_0)

fn final_state(&mut self, t: f64, y: Vec<f64>)

Called at the end of integration giving back the state taken in initial_state
