abstract = {<p style="text-align: justify;">This article presents a mixed finite volume method for solving second-order elliptic
equations with Neumann boundary conditions. The computational domains can be decomposed
into non-overlapping sub-domains or blocks and the diffusion tensors may be discontinuous across
the sub-domain boundaries. We define a conforming triangular partition on each sub-domains
independently, and employ the standard mixed finite volume method within each sub-domain.
On the interfaces between different sun-domains, the grids are non-matching. The Robin type
boundary conditions are imposed on the non-matching interfaces to enhance the continuity of the
pressure and flux. Both the solvability and the first order rate of convergence for this numerical
scheme are rigorously proved. Numerical experiments are provided to illustrate the error behavior
of this scheme and confirm our theoretical results.</p>},
