  ABSTRACT: This paper presents and analyzes a Discrete Duality Finite Volume (DDFV) method to solve 2D diffusion problems under prescribed Robin boundary conditions. The derivation of a symmetric discrete problem is established. The existence and uniqueness of a solution to this discrete problem are shown via the positive definiteness of its associated matrix. We show that the discrete scheme meets the Neumann problem when the parameter α→0 (and, in a sense, when α→∞ the Dirichlet problem). This work is a continuation of our work regarding the development of DDFV methods. The main innovation here is taking into account Robin’s boundary conditions. We provide a few steps of Matlab implementation and numerical tests to confirm the effectiveness of the method.
