Abstract: The authors describe the development of a 3D parallel Fluid–Structure–Interaction (FSI) solver and its application to benchmark problems. Fluid and solid domains are discretised using and edge-based finite-volume scheme for efficient parallel computation, with a hybrid of node- and element-based strains calculated in the solid model for accuracy. The Pressure-Projection Artificial Compressibility Split (PACS) algorithm [1] is used in the fluid domain and re-derived in an Arbitrary- Lagrangian–Eulerian (ALE) reference frame. A preconditioned GMRES algorithm is developed for matrix-free solver acceleration. The fluid and structural domains are strongly coupled with a fast mesh-movement technique employed in the fluid domain. The solver is parallelised for distributed-memory architectures.
