Stability of Finite Difference Methods
web.mit.edux(s <t). We can also consider the numerical domain of dependence of the solution at (xi,tn). Figure 22(a) shows the numerical domain of dependence of the FTBS method. A necessary condition for the convergence of a finite difference method for a hyperbolic PDE is that the numerical domain of dependence contains the mathematical domain of ...

Understanding the Finite-Difference Time-Domain Method
eecs.wsu.eduon the finite-difference time-domain (FDTD) method. The FDTD method makes approximations that force the solutions to be approximate, i.e., the method is inherently approximate. The results obtained from the FDTD method would be approximate even if we used computers that offered infinite numeric precision.

Finite Difference Method for Solving Differential Equations
mathforcollege.comThe finite difference method is used to solve ordinary differential equations that have conditions imposed on the boundary rather than at the initial point. These problems are called boundary-value problems. In this chapter, we solve second-order ordinary differential equations of the form . f x y y a x b dx d y = ( , , '), ≤ ≤ 2 2, (1)
