We learn in this chapter that DG cannot use the same representation of the Laplacian operator. Rather, we need to revisit first order derivatives and construc

That is, in the domain . ∈ [−1, +1] we are constrained to line elements. However, in two dimensions this door is flung wide open and we are now free to choose all sorts of polygons as the basic building blo

Analyse der Markt- und Positionssituation, of two-dimensional elliptic problems with the discontinuous Galerkin method. Although the extension to multi-dimensions is straightforward, to simplify the discussion we focus on two dimensions. This chapter focuses on the discretization of scalar elliptic problems (e.g., Poisson problem) using the

Strategische Ausrichtung als Erfolgsbasis,ly. In Ch. . we introduced the extension of the CG method to two dimensions by describing its implementation for elliptic partial differential equations (PDEs). In this chapter we extend the CG method for the application of hyperbolic equations in two dimensions. We also discuss the addition of diff
