The aim of this paper is to give a simple, introductory presentation of the extension of the Virtual Element Method to the discretisation of H(div)-conforming vector fields (or, more generally, of (n-1)- Cochains). As we shall see, the methods presented here can be seen as extensions of the so-called BDM family to deal with more general element geometries (such as polygons with an almost arbitrary geometry). For the sake of simplicity, we limit ourselves to the 2-dimensional case, with the aim of making the basic philosophy clear.

Abstract

The aim of this paper is to give a simple, introductory presentation of the extension of the Virtual Element Method to the discretisation of H(div)-conforming vector fields (or, more generally, of (n-1)- Cochains). As we shall see, the methods presented here can be seen as extensions of the so-called BDM family to deal with more general element geometries (such as polygons with an almost arbitrary geometry). For the sake of simplicity, we limit ourselves to the 2-dimensional case, with the aim of making the basic philosophy clear. However, we consider an arbitrary degree of accuracy k (the Virtual Element analogue of dealing with polynomials of arbitrary order in the Finite Element Framework).
