| This paper is the sequel of the paper [2] of S. Krell and the authors, where a family of 3D finite volume schemes on ``double'' meshes was constructed and the crucial discrete duality property was established. Heading towards applications, we state some discrete functional analysis tools (consistency results, Poincare and Sobolev embedding inequalities, discrete $W^{1,p}$ compactness, discrete $L^1$ compactness in space and time) for the DDFV scheme of [2]. We apply them to infer convergence of discretizations of nonlinear elliptic-parabolic problems of Leray-Lions kind. Applications to degenerate parabolic-hyperbolic PDEs and to a degenerate parabolic system known in electro-cardiology are briefly discussed. |
