Order of Accuracy and the Convergence Rate,s error is a measure of how well the difference scheme is approximating the differential equation, but by itself it doesn’t tell how well the . of the difference scheme approximates the . of the differential equation. This requires stability, and we have seen in the previous chapter, that there are

Approximation in Space, and . is a difference operator. This is called a ., or the .. The latter name originates from the graph in the . plane, where the discretization is shown by vertical, but continuous lines. It is assumed that the system (4.1) is solved by some standard method in time. In the following we shall discu

Boundary Treatment,as demonstrated in Chapter 4. The boundary conditions are more complicated, in particular for higher order approximations. Even if a high order approximation of a given boundary condition is easy to construct, we need extra numerical boundary conditions to define a unique numerical solution, since t

The Box Scheme,te. The reason for bringing it in, is that the error coefficient is very small compared to other second order methods because of the very compact structure. The small error coefficient makes it competitive with higher order schemes for many applications. Furthermore, the box structure allows for a v

Introduction to Other Numerical Methods, The chapter covers the most common and general methods, which are finite element methods (FEM), discontinuous Galerkin methods (DG), spectral methods and finite volume methods (FVM). More specialized methods, like the method of characteristics, are not included here.
