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 … See more • Partial differential equations • Crank–Nicolson method • Finite-difference time-domain method See more http://web.mit.edu/16.90/BackUp/www/pdfs/Chapter14.pdf
