We present here some results provided by a multiscale resolution method using both Finite Volumes and Finite Elements.
This method is aimed at solving very large diffusion problems with highly oscillating coefficients.
As an illustrative example, we simulate models of cement media, where very strong variations of diffusivity occur.
As a by-product of our simulations, we compute the effective diffusivities of these media.
After a short introduction, we present a theorical description of our method.
Numerical experiments on a two dimensional cement paste are presented subsequently.
The third section describes the implementation of our method in the calculus code MPCube and its application to a sample of mortar.
Finally, we discuss strengths and weaknesses of our method, and present our future works on this topic.

Abstract
We present here some results provided by a multiscale resolution method using both Finite Volumes and Finite Elements.
This method is aimed at solving very large diffusion problems with highly oscillating coefficients.
As an illustrative example, we simulate models of cement media, where very strong variations of diffusivity occur.
As a by-product of our simulations, we compute the effective diffusivities of these media.
After a short introduction, we present a theorical description of our method.
Numerical experiments on a two dimensional cement paste are presented subsequently.
The third section describes the implementation of our method in the calculus code MPCube and its application to a sample of mortar.
Finally, we discuss strengths and weaknesses of our method, and present our future works on this topic.
