Detailed Description

Abstract interface for time-integration schemes solving the 1D heat equation.

This interface abstracts away the difference between explicit/implicit schemes and 2-level/3-level time stepping schemes.

virtual Method::~Method ( )

virtualdefault

virtual std::string Method::name ( ) const

pure virtual

Get human-readable name of the scheme.

pure virtual

Computes the temperature field at the next time step (T^{n+1}).

Parameters

g	Grid metadata (spacing dx and node count Nx).
D	Thermal diffusivity [cm^2/h].
dt	Time step size [h].
Tprev	Temperature at time step n-1 (Read-only). Required only for 3-level schemes (Richardson, DuFort-Frankel). For 2-level schemes, this vector may be ignored.
Tcurr	Temperature at time step n (Read-only).
Tnext	Output vector to be filled with temperature at time step n+1.

virtual bool Method::uses_previous_step ( ) const

pure virtual

Indicates if the scheme requires data from time step n-1.

Returns: true For 3-level schemes (e.g., Richardson, DuFort-Frankel).; false For 2-level schemes (e.g., Laasonen, Crank-Nicolson).
