Coupling FVM and FEM using coupling code with Code Saturne and Code ASTER

Year: 2025

Type: article

Abstract: The mechanics of fluid–structure interactions (FSI) originated from the necessity to understand complex phenomena involving multiple scientific disciplines. In solid mechanics, fluids are often considered to have a negligible influence or are modeled in a simplified manner, while in fluid mechanics, solids are typically treated as boundary conditions. Although these approximations are valid in many cases, they become insufficient when strong interactions between solids and fluids occur, requiring a coupled approach for accurate modeling. This research investigates the behavior of fluid–structure interactions and presents a fully customized coupling algorithm integrating two open-source solvers: Code_Saturne for fluid dynamics and Code_Aster for structural analysis. The algorithm is implemented on the AUSTRAL cluster, hosted by CRIANN (Centre Régional Informatique et d’Applications Numériques de Normandie).
