A high-order finite difference formula can be obtained directly from a Taylor series expansion of the derivatives around the node of interest. As an example consider the one-dimensional mesh in Figure 3.12. We have an equal node spacing of Δ x and we will find an approximation to the first ...

WebNevertheless, it is convenient to have these alternative ways of expressing differences. For expressing differences symmetrically, there is a third operator δ, called the central difference operator, ... For time integration a second order backward difference formula is used. Here the Navier-Stokes equation are solved together with the energy ...
WebForward difference If a function (or data) is sampled at discrete points at intervals of length h, so that fn = f (nh), then the forward difference approximation to f ′ at the point nh is given by h f f f n n n − ′ ≈ +1. How accurate is this approximation? Obviously it depends on the size of h. Use the Taylor expansion of fn+1: ( ) ( )
