MATHEMATICA TUTORIAL, Part 1.3: Finite Difference Schemes

In numerical analysis, finite-difference methods (FDM) are a class of numerical techniques for solving differential equations by approximating derivatives with finite differences. Both the spatial domain and time interval (if applicable) are discretized, or broken into a finite number of steps, and the value of the solution at these discrete points is approximated by solving algebraic equations containing finite differences and values from nearby points.

WebEquation (B4.1.1) is called the Taylor series or Taylor’s formula. If the remainder is omitted, the right side of Eq. (B4.1.1) is the Taylor polynomial approximation to f (x). In essence, the theorem states that any smooth function can be ap-proximated as a polynomial. Equation (B4.1.2) is but one way, called the integral form,by WebThus a finite difference solution basically involves three steps: • Dividing the solution region into a grid of nodes. • Approximating the given differential equation by finite difference …
