Convergence of nonlinear finite volume schemes for heterogeneous anisotropic diffusion on general meshes

Abstract: In the present work, we deal with the convergence of cell-centered nonlinear finite volume schemes for anisotropic and heterogeneous diffusion operators. A general framework for the convergence study of finite volume methods is provided and used to establish the convergence of the new methods. Thorough assessment on a set of anisotropic heterogeneous problems as well as a comparison with linear finite volume schemes is provided.

“…Therefore, appropriate schemes have to be chosen application dependent. In general, the convergence of schemes can be proven if the scheme is consistent and coercive, as it has been done in [4,8,12,21]. In the following, we briefly describe such fundamental properties for cell-centered schemes (with discrete solution space (12)) and for HMM schemes (with discrete solution space (14)).…”

“…where D & C 0 ðXÞ is a test function space which is assumed to be dense in H 1 0 ðXÞ, and F K ;r ; F K;r are the discrete and exact flux functions, respectively. Furthermore, u D ¼ ðu T ; u E Þ 2 X D is defined as ðu T Þ K ¼ uðx K Þ for all K 2 T , and ðu E Þ r ¼ uðx r Þ for all r 2 E. More details can for example be found in [21].…”

“…The accuracy in the mildly anisotropic problem on 3D Kershaw meshes, ie, mesh D in Figure 6, is not so good as we expected and should be improved later. Up to now, the existence or convergence of the numerical solution for some nonlinear cell-centered FV schemes (see, eg, Blanc and Labourasse 6 and Schneider et al 46 ) has been analyzed. In the future, we will focus on these aspects for our vertex-centered positivity-preserving scheme.…”
