In numerical analysis, the FTCS (Forward Time Centered Space) method is a finite difference method used for numerically solving the heat equation and similar parabolic partial differential equations. It is a first-order method in time, explicit in time, and is conditionally stable when applied to the heat … See more The FTCS method is often applied to diffusion problems. As an example, for 1D heat equation, $${\displaystyle {\frac {\partial u}{\partial t}}=\alpha {\frac {\partial ^{2}u}{\partial x^{2}}}}$$ See more As derived using von Neumann stability analysis, the FTCS method for the one-dimensional heat equation is numerically stable if and only if the following condition is satisfied: See more • Partial differential equations • Crank–Nicolson method • Finite-difference time-domain method See more Webforward-in-time methods for the advection terms, for example, the Crowley schemes (Tremback et al. 1987), and the forward–backward scheme for the fast modes had significant instabilities, even with filtering.Yetthese and other forward-in-time schemes are attractive if a stable time-split methodology can be found.
