As it follows, for example, from Ainsworth et al. (2006), in this case the DG coincides with the finite-difference scheme on conventional (non-staggered) grid. This means that the problem can be ...

However, one needs to understand that finite element methods use a function, not the differential equation itself, to develop the approximate solution. This is unlike the finite difference methods, where the derivatives in the differential equations are approximated by finite divided difference methods.

The finite element method, originated in the structural calculation, is a very useful tool for modelling complicate geometries having independence from any coordinate system. This method is used to represent the spatial parameters with polynomial approximation of higher order for three dimensional elements with a triangular, quadrilateral or ...

The only difference between the finite-difference and finite element equations, written in this fashion, is the difference between the coefficients of the Ti term. To compare these terms on a common basis, we can set xII – xI = h in equation [65] and compute the ratio 2α/β as follows.
