| Abstract | Multi-physics, high-fidelity simulations become an increasingly important part of industrial design processes. Simulations of fluid-structure interactions (FSI) are of great practical significance – especially within the aeronautics industry – and because of their complexity they require huge computational resources. On the basis of OpenFOAM a partitioned, strongly coupled solver for transient FSI simulations with independent meshes for the fluid and solid domains has been implemented. Using two different kinds of model sets, a geometrically simple 3D beam with quadratic cross section and a geometrically complex aircraft configuration, runtime and scalability characteristics are investigated. By modifying the implementation of OpenFOAM’s interprocessor communication the scalability limit could be increased by one order of magnitude (from below 512 to above 4096 processes) for a model with 61 million cells.
