We consider a non-linear finite volume (FV) scheme for stationary diffusion equation. We prove that the scheme monotone, i.e. it preserves positivity of analytical solutions on arbitrary triangular meshes for strongly anisotropic at. heterogeneous full tensor coefficients. The scheme is extended to regular star-shaped polygonal meshes and isotropic heterogeneous coefficients. (C) 2007 Elsevier Inc. All rights reserved.
