The purpose of this study is to re-establish some definite relationships between Finite Difference and Finite Element Methods.
As such, it may be considered as a continuation of my 'Series on Unified Numerical Approximations' (SUNA).
A new result is the generalization of Patankar's F.V. schemes for convection and diffusion (also called confusion), for meshes consisting of F.E. triangles.
