Crank–Nicolson method - Wikipedia

WebIn numerical analysis, the Crank–Nicolson method is a finite difference method used for numerically solving the heat equation and similar partial differential equations. It is a second-order method in time. It is implicit in time, can be written as an implicit Runge–Kutta method, and it is numerically stable.The method was developed by John Crank and … WebFor the forward Euler method we get: − 2 ≤ − α Δ t 2 Δ x 2 ( 1 − cos ( k m Δ x)) ≤ 0 To ensure that these constraints are satisfied for all values of m, the following restriction on the time step is required: Δ t ≤ Δ x 2 2 α (Forward Euler mehod) For the RK4 time integration method we get: Δ t ≤ 2.79 Δ x 2 4 α (RK4 mehod) Web2.
