Discretization of the geometrical quantities

  Since we assume that the transformation T is not explicitly known, but only implicitly by the mapping of the co-ordinates of the vertices, it is necessary to discretize the geometrical quantities mentioned in Section 2. In the ISNaS incompressible code there are several ways of computing these quantities. The choice of which of these methods is used is defined by the input parameter geotype. In this section we shall treat the various possibilities as function of geotype. We distinguish between 2D and 3D.
