Immersive Visualisation of Bristled Wing Dynamics using Fluid-Structure Interaction

Visualising the aerodynamics of bristled wings remains challenging due to the complex three-dimensional interaction between airflow and flexible bristles. Conventional analysis typically relies on 2D visualisation, which limits spatial understanding of airflow leakage and deformation patterns. This paper presents an immersive digital twin platform for exploratory visualisation of fluid–structure interaction (FSI) simulations of bristled wings using NVIDIA Omniverse. The proposed system integrates high-performance FSI simulation data generated with the OpenFPCI solver, post-processed in ParaView, and rendered in a photorealistic virtual laboratory environment. A virtual reality (VR) headset is coupled with an omnidirectional treadmill to enable natural locomotion, allowing users to physically walk through and around the simulated wing structure. Custom Omniverse extensions support real-time user movement and object interaction within the virtual space. Preliminary demonstrations show that the immersive environment enables intuitive multi-scale inspection of airflow patterns and bristle deformation from arbitrary viewpoints. While no formal user study is conducted, the platform demonstrates the feasibility of combining digital twins, immersive locomotion, and high-fidelity FSI data to support qualitative exploration of complex aerodynamic phenomena.
