Abstract: Fluid-structure interaction (FSI) studies often require coupling specialized fluid and structural solvers while preserving reproducibility across long high-performance-computing runs. This article presents a customizable explicit Dirichlet-Neumann framework coupling Code_Saturne and Code_Aster. The software automates non-matching interface-field transfer, transient structural dynamics, displacement relaxation, local mesh morphing, restart management, tracking, archiving, and Slurm job sequencing. Circular-cylinder and Turek-Hron-inspired examples verify the data-transfer sequence and illustrate the operating range of the explicit formulation. The framework is intended for weakly to moderately coupled FSI studies and provides a transparent basis for future implicit or quasi-Newton extensions.
