A new approach to model geomaterials with heterogeneous properties in thermo-hydro-mechanical coupled problems

The main objective of this article is to present a new approach model coupled thermo-hydro-mechanical problems considering geomaterials with heterogeneous properties. This has been implemented in the software CODE_BRIGHT and it provides possibility spatially correlated field porosity, following normal distribution. spatial correlation can be isotropic or anisotropic. An important feature that material properties such as intrinsic permeability, thermal conductivity, diffusivity, retention curve, elastic modulus cohesion are defined function porosity and, thus, they become eventually, A validation exercise other basic numerical examples have carried out illustrate possibilities proposed approach. results, which compared homogeneous case, show fields relevant different modelling problems, especially problems.
