Ultra deepwater subsea CFD riser analysis requires an accurate and scalable approach to capture the complex effects of flow separation and resulting Vortex-Induced Vibration (VIV) in order to appropriately assess riser fatigue life. Simulating the multi-physical phenomena of VIV requires a highly-scalable solver with fully-coupled Fluid/Structure Interaction (FSI) capability to analyze and adequately describe the nonlinear response due to marine currents, riser shapes, and the possible influence of multiple subsea structures. We present a state-of-the-art solver approach as well as optimized HPC implementation to do exactly that. We discuss the impact of both solver and HPC technologies on performance, accuracy, and scalability.
