Master 2 internship at EDF and LJAD
Within the R&D of EDF, the LNHE department (Laboratoire National d’Hydraulique et Environnement) is studying the impact on the environment of the industrial facilities. In this framework, the team in charge of hydrogeolocal studies develops simulation tools to model the flows in the neighbourhood of industrial facilities. These simulations are performed using the SALOME platform ( for the pre and post processing as well as the « Groundwater Flow » module of Code_Saturne ( for the processor. Code_Saturne, developed by the MFEE department, is the reference code at EDF R&D for computational fluid dynamics. The soil moisture content, the pressure and the velocity of the grounwater flow are obtained using the Richards equation. The simulations are based on the finite volume discretization and are performed in parallel on distributed architectures.
The objective of the proposed internship is to improve the robustness of these simulations using a Newton type algorithm combined with a smart choice of the primary unknown. The new algorithm will be tested and compared with classical approaches on realistic test cases including heterogeneities and anisotropy of the medium and non conformity of the mesh.
