MOX report on the convergence of OpenFOAM discretisations of the Laplace operator on non-orthogonal meshes

A new MOX report proving the convergence of cell centered finite volume discretisations used in the OpenFOAM software for the Laplace operator also on non-orthogonal meshes as been published by Alessandro Della Rocca and Luca Bonaventura.  The report can be downloaded from
