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 … Web1 de jan. de 2014 · Schwarz also gave an analogy of his alternating method with a physical device, as indicated on the right in Fig. 5: a vacuum pump with two cylinders. In order to create a vacuum in the inner chamber, one has to alternatingly pump with the two cylinders, similar to the subdomain solves in the alternating method. WebAbstract.
